Improve run time of coordinator duty MarkAsUnusedOvershadowedSegments (#13287)
In clusters with a large number of segments, the duty `MarkAsUnusedOvershadowedSegments`
can take a long very long time to finish. This is because of the costly invocation of 
`timeline.isOvershadowed` which is done for every used segment in every coordinator run.

Changes
- Use `DataSourceSnapshot.getOvershadowedSegments` to get all overshadowed segments
- Iterate over this set instead of all used segments to identify segments that can be marked as unused
- Mark segments as unused in the DB in batches rather than one at a time
- Refactor: Add class `SegmentTimeline` for ease of use and readability while using a
`VersionedIntervalTimeline` of segments.

Remove basePersistDirectory from tuning configs. (#13040)
* Remove basePersistDirectory from tuning configs.

Since the removal of CliRealtime, it serves no purpose, since it is
always overridden in production using withBasePersistDirectory given
some subdirectory of the task work directory.

Removing this from the tuning config has a benefit beyond removing
no-longer-needed logic: it also avoids the side effect of empty
"druid-realtime-persist" directories getting created in the systemwide
temp directory.

* Test adjustments to appropriately set basePersistDirectory.

* Remove unused import.

* Fix RATC constructor.

Modular Calcite Test Framework (#12965)
* Refactor Calcite test "framework" for planner tests

Refactors the current Calcite tests to make it a bit easier
to adjust the set of runtime objects used within a test.

* Move data creation out of CalciteTests into TestDataBuilder
* Move "framework" creation out of CalciteTests into
  a QueryFramework
* Move injector-dependent functions from CalciteTests
  into QueryFrameworkUtils
* Wrapper around the planner factory, etc. to allow
  customization.
* Bulk of the "framework" created once per class rather
  than once per test.
* Refactor tests to use a test builder
* Change all testQuery() methods to use the test builder.
Move test execution & verification into a test runner.

Redesign QueryContext class (#13071)
We introduce two new configuration keys that refine the query context security model controlled by druid.auth.authorizeQueryContextParams. When that value is set to true then two other configuration options become available:

druid.auth.unsecuredContextKeys: The set of query context keys that do not require a security check. Use this for the "white-list" of key to allow. All other keys go through the existing context key security checks.
druid.auth.securedContextKeys: The set of query context keys that do require a security check. Use this when you want to allow all but a specific set of keys: only these keys go through the existing context key security checks.
Both are set using JSON list format:

druid.auth.securedContextKeys=["secretKey1", "secretKey2"]
You generally set one or the other values. If both are set, unsecuredContextKeys acts as exceptions to securedContextKeys.

In addition, Druid defines two query context keys which always bypass checks because Druid uses them internally:

Make http options the default configurations (#13092)
Druid currently uses Zookeeper dependent options as the default.
This commit updates the following to use HTTP as the default instead.
- task runner. `druid.indexer.runner.type=remote -> httpRemote`
- load queue peon. `druid.coordinator.loadqueuepeon.type=curator -> http`
- server inventory view. `druid.serverview.type=curator -> http`

Add test framework to simulate segment loading and balancing (#13074)
Fixes #12822 

The framework added here make it easy to write tests that verify the behaviour and interactions
of the following entities under various conditions:
- `DruidCoordinator`
- `HttpLoadQueuePeon`, `LoadQueueTaskMaster`
- coordinator duties: `BalanceSegments`, `RunRules`, `UnloadUnusedSegments`, etc.
- datasource retention rules: `LoadRule`, `DropRule`

Changes:
Add the following main classes:
- `CoordinatorSimulation` and related interfaces to dictate behaviour of simulation
- `CoordinatorSimulationBuilder` to build a simulation.
- `BlockingExecutorService` to keep submitted tasks in queue and execute them
  only when explicitly invoked.

Add tests:
- `CoordinatorSimulationBaseTest`, `SegmentLoadingTest`, `SegmentBalancingTest`
- `SegmentLoadingNegativeTest` to contain tests which assert the existing erroneous behaviour
of segment loading. Once the behaviour is fixed, these tests will be moved to the regular
`SegmentLoadingTest`.

Please refer to the README.md in `org.apache.druid.server.coordinator.simulate` for more details

Faster fix for dangling tasks upon supervisor termination (#13072)
This commit fixes issues with delayed supervisor termination during certain transient states.
Tasks can be created during supervisor termination and left behind since the cleanup may
not consider these newly added tasks.

#12178 added a lock for the entire process of task creation to prevent such dangling tasks.
But it also introduced a deadlock scenario as follows:
- An invocation of `runInternal` is in progress.
- A `stop` request comes, acquires `stateChangeLock` and submit a `ShutdownNotice`
- `runInternal` keeps waiting to acquire the `stateChangeLock`
- `ShutdownNotice` remains stuck in the notice queue because `runInternal` is still running
- After some timeout, the supervisor goes through a forced termination

Fix:
 * `SeekableStreamSupervisor.runInternal` - do not try to acquire lock if supervisor is already stopping
 * `SupervisorStateManager.maybeSetState` - do not allow transitions from STOPPING state

Expose HTTP Response headers from SqlResource (#13052)
* Expose HTTP Response headers from SqlResource

This change makes the SqlResource expose HTTP response
headers in the same way that the QueryResource exposes them.

Fundamentally, the change is to pipe the QueryResponse
object all the way through to the Resource so that it can
populate response headers.  There is also some code
cleanup around DI, as there was a superfluous FactoryFactory
class muddying things up.

json_value adjustments (#12968)
* json_value adjustments
changes:
* native json_value expression now has optional 3rd argument to specify type, which will cast all values to the specified type
* rework how JSON_VALUE is wired up in SQL. Now we are using a custom convertlet to translate JSON_VALUE(... RETURNING type) into dedicated JSON_VALUE_BIGINT, JSON_VALUE_DOUBLE, JSON_VALUE_VARCHAR, JSON_VALUE_ANY instead of using the calcite StandardConvertletTable that wraps JSON_VALUE_ANY in a CAST, so that we preserve the typing of JSON_VALUE to pass down to the native expression as the 3rd argument

* fix bug

* checkstyle

* validate that options to json_value are the supported options rather than ignore them

Add the new integration test framework (#12368)
This commit is a first draft of the revised integration test framework which provides:
- A new directory, integration-tests-ex that holds the new integration test structure. (For now, the existing integration-tests is left unchanged.)
- Maven module druid-it-tools to hold code placed into the Docker image.
- Maven module druid-it-image to build the Druid-only test image from the tarball produced in distribution. (Dependencies live in their "official" image.)
- Maven module druid-it-cases that holds the revised tests and the framework itself. The framework includes file-based test configuration, test-specific clients, test initialization and updated versions of some of the common test support classes.

The integration test setup is primarily a huge mass of details. This approach refactors many of those details: from how the image is built and configured to how the Docker Compose scripts are structured to test configuration. An extensive set of "readme" files explains those details. Rather than repeat that material here, please consult those files for explanations.

#12912 Fix KafkaEmitter not emitting queryType for a native query (#12915)
Fixes KafkaEmitter not emitting queryType for a native query. The Event to JSON serialization was extracted to the external class: EventToJsonSerializer. This was done to simplify the testing logic for the serialization as well as extract the responsibility of serialization to the separate class.

The logic builds ObjectNode incrementally based on the event .toMap method. Parsing each entry individually ensures that the Jackson polymorphic annotations are respected. Not respecting these annotation caused the missing of the queryType from output event.

Introducing Storage connector Interface (#12874)
In the current druid code base, we have the interface DataSegmentPusher which allows us to push segments to the appropriate deep storage without the extension being worried about the semantics of how to push too deep storage.

While working on #12262, whose some part of the code will go as an extension, I realized that we do not have an interface that allows us to do basic "write, get, delete, deleteAll" operations on the appropriate deep storage without let's say pulling the s3-storage-extension dependency in the custom extension.

Hence, the idea of StorageConnector was born where the storage connector sits inside the druid core so all extensions have access to it.

Each deep storage implementation, for eg s3, GCS, will implement this interface.
Now with some Jackson magic, we bind the implementation of the correct deep storage implementation on runtime using a type variable.

Improved Java 17 support and Java runtime docs. (#12839)
* Improved Java 17 support and Java runtime docs.

1) Add a "Java runtime" doc page with information about supported
   Java versions, garbage collection, and strong encapsulation..

2) Update asm and equalsverifier to versions that support Java 17.

3) Add additional "--add-opens" lines to surefire configuration, so
   tests can pass successfully under Java 17.

4) Switch openjdk15 tests to openjdk17.

5) Update FrameFile to specifically mention Java runtime incompatibility
   as the cause of not being able to use Memory.map.

6) Update SegmentLoadDropHandler to log an error for Errors too, not
   just Exceptions. This is important because an IllegalAccessError is
   encountered when the correct "--add-opens" line is not provided,
   which would otherwise be silently ignored.

7) Update example configs to use druid.indexer.runner.javaOptsArray
   instead of druid.indexer.runner.javaOpts. (The latter is deprecated.)

* Adjustments.

* Use run-java in more places.

* Add run-java.

* Update .gitignore.

* Exclude hadoop-client-api.

Brought in when building on Java 17.

* Swap one more usage of java.

* Fix the run-java script.

* Fix flag.

* Include link to Temurin.

* Spelling.

* Update examples/bin/run-java

Use nonzero default value of maxQueuedBytes. (#12840)
* Use nonzero default value of maxQueuedBytes.

The purpose of this parameter is to prevent the Broker from running out
of memory. The prior default is unlimited; this patch changes it to a
relatively conservative 25MB.

This may be too low for larger clusters. The risk is that throughput
can decrease for queries with large resultsets or large amounts of intermediate
data. However, I think this is better than the risk of the prior default, which
is that these queries can cause the Broker to go OOM.

Peons should not report SysMonitor stats since MiddleManager reports them. (#12802)
Sysmonitor stats (mem, fs, disk, net, cpu, swap, sys, tcp) are reported by all Druid processes, including Peons that are ephemeral in nature. Since Peons always run on the same host as the MiddleManager that spawned them and is unlikely to change, the SyMonitor metrics emitted by Peon are merely duplicates. This is often not a problem except when machines are super-beefy. Imagine a 64-core machine and 32 workers running on this machine. now you will have each Peon reporting metrics for each core. that's an increase of (32 * 64)x in the number of metrics. This leads to a metric explosion.

This PR updates MetricsModule to check node role running while registering SysMonitor and not to load any existing SysMonitor$Stats.

Unregisters `RealtimeMetricsMonitor`, `TaskRealtimeMetricsMonitor` on Indexers after task completion (#12743)
Few indexing tasks register RealtimeMetricsMonitor or TaskRealtimeMetricsMonitor with the process’s MonitorScheduler when they start. These monitors never unregister themselves (they always return true, they'd need to return false to unregister). Each of these monitors emits a set of metrics once every druid.monitoring.emissionPeriod.
As a result, after executing several tasks for a while, Indexer emits metrics of these tasks even after they're long gone.

Proposed Solution
Since one should be able to obtain the last round of ingestion metrics after the task unregisters the monitor, introducing lastRoundMetricsToBePushed variable to keep track of the same and overriding the AbstractMonitor.monitor method in RealtimeMetricsMonitor, TaskRealtimeMetricsMonitor to implement the new logic.

Mid-level service client and updated high-level clients. (#12696)
* Mid-level service client and updated high-level clients.

Our servers talk to each other over HTTP. We have a low-level HTTP
client (HttpClient) that is super-asynchronous and super-customizable
through its handlers. It's also proven to be quite robust: we use it
for Broker -> Historical communication over the wide variety of query
types and workloads we support.

But the low-level client has no facilities for service location or
retries, which means we have a variety of high-level clients that
implement these in their own ways. Some high-level clients do a better
job than others. This patch adds a mid-level ServiceClient that makes
it easier for high-level clients to be built correctly and harmoniously,
and migrates some of the high-level logic to use ServiceClients.

Main changes:

1) Add ServiceClient org.apache.druid.rpc package. That package also
   contains supporting stuff like ServiceLocator and RetryPolicy
   interfaces, and a DiscoveryServiceLocator based on
   DruidNodeDiscoveryProvider.

2) Add high-level OverlordClient in org.apache.druid.rpc.indexing.

3) Indexing task client creator in TaskServiceClients. It uses
   SpecificTaskServiceLocator to find the tasks. This improves on
   ClientInfoTaskProvider by caching task locations for up to 30 seconds
   across calls, reducing load on the Overlord.

4) Rework ParallelIndexSupervisorTaskClient to use a ServiceClient
   instead of extending IndexTaskClient.

5) Rework RemoteTaskActionClient to use a ServiceClient instead of
   DruidLeaderClient.

6) Rework LocalIntermediaryDataManager, TaskMonitor, and
   ParallelIndexSupervisorTask. As a result, MiddleManager, Peon, and
   Overlord no longer need IndexingServiceClient (which internally used
   DruidLeaderClient).

There are some concrete benefits over the prior logic, namely:

- DruidLeaderClient does retries in its "go" method, but only retries
  exactly 5 times, does not sleep between retries, and does not retry
  retryable HTTP codes like 502, 503, 504. (It only retries IOExceptions.)
  ServiceClient handles retries in a more reasonable way.

- DruidLeaderClient's methods are all synchronous, whereas ServiceClient
  methods are asynchronous. This is used in one place so far: the
  SpecificTaskServiceLocator, so we don't need to block a thread trying
  to locate a task. It can be used in other places in the future.

- HttpIndexingServiceClient does not properly handle all server errors.
  In some cases, it tries to parse a server error as a successful
  response (for example: in getTaskStatus).

- IndexTaskClient currently makes an Overlord call on every task-to-task
  HTTP request, as a way to find where the target task is. ServiceClient,
  through SpecificTaskServiceLocator, caches these target locations
  for a period of time.

* Style adjustments.

* For the coverage.

* Adjustments.

* Better behaviors.

* Fixes.

Fix expiry timeout bug in LocalIntermediateDataManager (#12722)
The expiry timeout is compared against the current time but the condition is reversed.
This means that as soon as a supervisor task finishes, its partitions are cleaned up,
irrespective of the specified `intermediaryPartitionTimeout` period.

After these changes, the `intermediaryPartitionTimeout` will start getting honored.

Changes
* Fix the condition
* Add tests to verify the new correct behaviour
* Reduce the default expiry timeout from P1D to PT5M
   to retain current behaviour in case of default configs.

Optimize overlord GET /tasks memory usage (#12404)
The web-console (indirectly) calls the Overlord’s GET tasks API to fetch the tasks' summary which in turn queries the metadata tasks table. This query tries to fetch several columns, including payload, of all the rows at once. This introduces a significant memory overhead and can cause unresponsiveness or overlord failure when the ingestion tab is opened multiple times (due to several parallel calls to this API)

Another thing to note is that the task table (the payload column in particular) can be very large. Extracting large payloads from such tables can be very slow, leading to slow UI. While we are fixing the memory pressure in the overlord, we can also fix the slowness in UI caused by fetching large payloads from the table. Fetching large payloads also puts pressure on the metadata store as reported in the community (Metadata store query performance degrades as the tasks in druid_tasks table grows · Issue #12318 · apache/druid )

The task summaries returned as a response for the API are several times smaller and can fit comfortably in memory. So, there is an opportunity here to fix the memory usage, slow ingestion, and under-pressure metadata store by removing the need to handle large payloads in every layer we can. Of course, the solution becomes complex as we try to fix more layers. With that in mind, this page captures two approaches. They vary in complexity and also in the degree to which they fix the aforementioned problems.

make query context changes backwards compatible (#12564)
Adds a default implementation of getQueryContext, which was added to the Query interface in #12396. Query is marked with @ExtensionPoint, and lately we have been trying to be less volatile on these interfaces by providing default implementations to be more chill for extension writers.

The way this default implementation is done in this PR is a bit strange due to the way that getQueryContext is used (mutated with system default and system generated keys); the default implementation has a specific object that it returns, and I added another temporary default method isLegacyContext that checks if the getQueryContext returns that object or not. If not, callers fall back to using getContext and withOverriddenContext to set these default and system values.

I am open to other ideas as well, but this way should work at least without exploding, and added some tests to ensure that it is wired up correctly for QueryLifecycle, including the context authorization stuff.

The added test shows the strange behavior if query context authorization is enabled, mainly that the system default and system generated query context keys also need to be granted as permissions for things to function correctly. This is not great, so I mentioned it in the javadocs as well. Not sure if it needs to be called out anywhere else.

Fix usage of maxColumnsToMerge in auto-compaction tuning config (#12551)
Issue: 
Even though `CompactionTuningConfig` allows a `maxColumnsToMerge` config
(to optimize memory usage, particulary for datasources with many dimensions),
the corresponding client object `ClientCompactionTaskQueryTuningConfig`
(used by the coordinator duty `CompactSegments` to trigger auto-compaction)
does not contain this field. Thus, the value of `maxColumnsToMerge` specified
in any datasource compaction config is ignored.

Changes:
- Add field `maxColumnsToMerge` in `ClientCompactionTaskQueryTuningConfig`
  and `UserCompactionTaskQueryTuningConfig`
- Fix tests

Free ByteBuffers in tests and fix some bugs. (#12521)
* Ensure ByteBuffers allocated in tests get freed.

Many tests had problems where a direct ByteBuffer would be allocated
and then not freed. This is bad because it causes flaky tests.

To fix this:

1) Add ByteBufferUtils.allocateDirect(size), which returns a ResourceHolder.
   This makes it easy to free the direct buffer. Currently, it's only used
   in tests, because production code seems OK.

2) Update all usages of ByteBuffer.allocateDirect (off-heap) in tests either
   to ByteBuffer.allocate (on-heap, which are garbaged collected), or to
   ByteBufferUtils.allocateDirect (wherever it seemed like there was a good
   reason for the buffer to be off-heap). Make sure to close all direct
   holders when done.

* Changes based on CI results.

* A different approach.

* Roll back BitmapOperationTest stuff.

* Try additional surefire memory.

* Revert "Roll back BitmapOperationTest stuff."

Allow coordinator to be configured to kill segments in future (#10877)
Allow a Druid cluster to kill segments whose interval_end is a date in the future. This can be done by setting druid.coordinator.kill.durationToRetain to a negative period. For example PT-24H would allow segments to be killed if their interval_end date was 24 hours or less into the future at the time that the kill task is generated by the system.

A cluster operator can also disregard the druid.coordinator.kill.durationToRetain entirely by setting a new configuration, druid.coordinator.kill.ignoreDurationToRetain=true. This ignores interval_end date when looking for segments to kill, and instead is capable of killing any segment marked unused. This new configuration is off by default, and a cluster operator should fully understand and accept the risks if they enable it.

GroupBy: Reduce allocations by reusing entry and key holders. (#12474)
* GroupBy: Reduce allocations by reusing entry and key holders.

Two main changes:

1) Reuse Entry objects returned by various implementations of
   Grouper.iterator.

2) Reuse key objects contained within those Entry objects.

This is allowed by the contract, which states that entries must be
processed and immediately discarded. However, not all call sites
respected this, so this patch also updates those call sites.

One particularly sneaky way that the old code retained entries too long
is due to Guava's MergingIterator and CombiningIterator. Internally,
these both advance to the next value prior to returning the current
value. So, this patch addresses that in two ways:

1) For merging, we have our own implementation MergeIterator already,
   although it had the same problem. So, this patch updates our
   implementation to return the current item prior to advancing to the
   next item. It also adds a forbidden-api entry to ensure that this
   safer implementation is used instead of Guava's.

2) For combining, we address the problem in a different way: by copying
   the key when creating the new, combined entry.

* Attempt to fix test.

* Remove unused import.

Reduce allocations due to Jackson serialization. (#12468)
* Reduce allocations due to Jackson serialization.

This patch attacks two sources of allocations during Jackson
serialization:

1) ObjectMapper.writeValue and JsonGenerator.writeObject create a new
   DefaultSerializerProvider instance for each call. It has lots of
   fields and creates pressure on the garbage collector. So, this patch
   adds helper functions in JacksonUtils that enable reuse of
   SerializerProvider objects and updates various call sites to make
   use of this.

2) GroupByQueryToolChest copies the ObjectMapper for every query to
   install a special module that supports backwards compatibility with
   map-based rows. This isn't needed if resultAsArray is set and
   all servers are running Druid 0.16.0 or later. This release was a
   while ago. So, this patch disables backwards compatibility by default,
   which eliminates the need to copy the heavyweight ObjectMapper. The
   patch also introduces a configuration option that allows admins to
   explicitly enable backwards compatibility.

* Add test.

* Update additional call sites and add to forbidden APIs.

Add support for authorizing query context params (#12396)
The query context is a way that the user gives a hint to the Druid query engine, so that they enforce a certain behavior or at least let the query engine prefer a certain plan during query planning. Today, there are 3 types of query context params as below.

Default context params. They are set via druid.query.default.context in runtime properties. Any user context params can be default params.
User context params. They are set in the user query request. See https://druid.apache.org/docs/latest/querying/query-context.html for parameters.
System context params. They are set by the Druid query engine during query processing. These params override other context params.
Today, any context params are allowed to users. This can cause 
1) a bad UX if the context param is not matured yet or 
2) even query failure or system fault in the worst case if a sensitive param is abused, ex) maxSubqueryRows.

This PR adds an ability to limit context params per user role. That means, a query will fail if you have a context param set in the query that is not allowed to you. To do that, this PR adds a new built-in resource type, QUERY_CONTEXT. The resource to authorize has a name of the context param (such as maxSubqueryRows) and the type of QUERY_CONTEXT. To allow a certain context param for a user, the user should be granted WRITE permission on the context param resource. Here is an example of the permission.

{
  "resourceAction" : {
    "resource" : {
      "name" : "maxSubqueryRows",
      "type" : "QUERY_CONTEXT"
    },
    "action" : "WRITE"
  },
  "resourceNamePattern" : "maxSubqueryRows"
}
Each role can have multiple permissions for context params. Each permission should be set for different context params.

When a query is issued with a query context X, the query will fail if the user who issued the query does not have WRITE permission on the query context X. In this case,

HTTP endpoints will return 403 response code.
JDBC will throw ForbiddenException.
Note: there is a context param called brokerService that is used only by the router. This param is used to pin your query to run it in a specific broker. Because the authorization is done not in the router, but in the broker, if you have brokerService set in your query without a proper permission, your query will fail in the broker after routing is done. Technically, this is not right because the authorization is checked after the context param takes effect. However, this should not cause any user-facing issue and thus should be OK. The query will still fail if the user doesn’t have permission for brokerService.

The context param authorization can be enabled using druid.auth.authorizeQueryContextParams. This is disabled by default to avoid any hassle when someone upgrades his cluster blindly without reading release notes.

Increase default DatasourceCompactionConfig.inputSegmentSizeBytes to Long.MAX_VALUE (#12381)
The current default value of inputSegmentSizeBytes is 400MB, which is pretty
low for most compaction use cases. Thus most users are forced to override the
default.

The default value is now increased to Long.MAX_VALUE.

Facilitate lazy initialization of connections to mitigate overwhelming of Coordinator (#12298)
Add config for eager / lazy connection initialization in ResourcePool

Description
Currently, when multiple tasks are launched, each of them eagerly initializes a full pool's worth of connections to the coordinator.

While this is acceptable when the parameter for number of eagerConnections (== maxSize) is small, this can be problematic in environments where it's a large value (say 1000) and multiple tasks are launched simultaneously, which can cause a large number of connections to be created to the coordinator, thereby overwhelming it.

Patch
Nodes like the broker may require eager initialization of resources and do not create connections with the Coordinator.
It is unnecessary to do this with other types of nodes.

A config parameter eagerInitialization is added, which when set to true, initializes the max permissible connections when ResourcePool is initialized.

If set to false, lazy initialization of connection resources takes place.

NOTE: All nodes except the broker have this new parameter set to false in the quickstart as part of this PR

Algorithm
The current implementation relies on the creation of maxSize resources eagerly.

The new implementation's behaviour is as follows:

If a resource has been previously created and is available, lend it.
Else if the number of created resources is less than the allowed parameter, create and lend it.
Else, wait for one of the lent resources to be returned.

Always reopen stream in FileUtils.copyLarge, RetryingInputStream. (#12307)
* Always reopen stream in FileUtils.copyLarge, RetryingInputStream.

When an InputStream throws an exception from one of its read methods,
we should assume it's bad and reopen it.

The main changes here are:

- In FileUtils.copyLarge, replace InputStream with InputStreamSupplier.
- In RetryingInputStream, collapse retryCondition and resetCondition
  into a single condition. Also, make it required, since every usage
  is passing in a specific condition anyway.

* Test fixes.

Make ParseExceptions more informative (#12259)
This PR aims to make the ParseExceptions in Druid more informative, by adding additional information (metadata) to the ParseException, which can contain additional information about the exception. For example - the path of the file generating the issue, the line number (where it can be easily fetched - like CsvReader)

Following changes are addressed in this PR:

A new class CloseableIteratorWithMetadata has been created which is like CloseableIterator but also has a metadata method that returns a context Map<String, Object> about the current element returned by next().
IntermediateRowParsingReader#read() now attaches the InputEntity and the "record number" which created the exception (while parsing them), and IntermediateRowParsingReader#sample attaches the InputEntity (but not the "record number").
TextReader (and its subclasses), which is a specific implementation of the IntermediateRowParsingReader also include the line number which caused the generation of the error.
This will also help in triaging the issues when InputSourceReader generates ParseException because it can point to the specific InputEntity which caused the exception (while trying to read it).

Fix long overflow in SegmentCostCache.Bucket.toLocalInterval (#12257)
Problem:
When using a `CachingCostBalancerStrategy` with segments of granularity ALL,
no segment gets loaded.
- With granularity ALL, segments of eternity interval are created which have 
  `start = Long.MIN_VALUE / 2` and `end = Long.MAX_VALUE / 2`.
- For cost calculation in the balancer strategy, `toLocalInterval()` method is invoked where
  `Long.MIN_VALUE / 2` or `Long.MAX_VALUE / 2` cause an overflow thus resulting in no overlap.
- The strategy is unable to find any eligible server for loading a given segment.

Fix:
- Reverse order of operations to divide by `MILLIS_FACTOR` (~10^8) first,
   then do the subtraction to prevent Long overflow.

Improve memory estimates in Aggregator and DimensionIndexer (#12073)
Fixes #12022  

### Description
The current implementations of memory estimation in `OnHeapIncrementalIndex` and `StringDimensionIndexer` tend to over-estimate which leads to more persistence cycles than necessary.

This PR replaces the max estimation mechanism with getting the incremental memory used by the aggregator or indexer at each invocation of `aggregate` or `encode` respectively.

### Changes
- Add new flag `useMaxMemoryEstimates` in the task context. This overrides the same flag in DefaultTaskConfig i.e. `druid.indexer.task.default.context` map
- Add method `AggregatorFactory.factorizeWithSize()` that returns an `AggregatorAndSize` which contains
  the aggregator instance and the estimated initial size of the aggregator
- Add method `Aggregator.aggregateWithSize()` which returns the incremental memory used by this aggregation step
- Update the method `DimensionIndexer.processRowValsToKeyComponent()` to return the encoded key component as well as its effective size in bytes
- Update `OnHeapIncrementalIndex` to use the new estimations only if `useMaxMemoryEstimates = false`

Fix load-drop-load sequence for same segment and historical in http loadqueue peon (#11717)
Fixes an issue where a load-drop-load sequence for a segment and historical doesn't work correctly for http based load queue peon. The first cycle of load-drop works fine - the problem comes when there is an attempt to reload the segment. The historical caches load success for some recent segments and makes the reload as a no-op. But it doesn't consider that fact that the segment was also dropped in between the load requests.
This change invalidates the cache after a client tries to fetch a success result.

Fix bad lookup config fails task (#12021)
This PR fixes an issue in which if a lookup is configured incorreclty; does not serialize properly when being pulled by peon node, it causes the task to fail. The failure occurs because the peon and other leaf nodes (broker, historical), have retry logic that continues to retry the lookup loading for 3 minutes by default. The http listener thread on the peon task is not started until lookup loading completes, by default, the overlord waits 1 minute by default, to communicate with the peon task to get the task status, after which is orders the task to shut down, causing the ingestion task to fail.

To fix the issue, we catch the exception serialization error, and do not retry. Also fixed an issue in which a bad lookup config interferes with any other good lookup configs from being loaded.

Human-readable and actionable SQL error messages (#11911)
This PR does two things

1. It adds the capability to surface missing features in SQL to users - The calcite planner will explore through multiple rules to convert a logical SQL query to a druid native query. Some rules change the shape of the query itself, optimize it and some rules are responsible for translating the query into a druid native query. These are DruidQueryRule, DruidOuterQueryRule, DruidJoinRule, DruidUnionDataSourceRule, DruidUnionRule etc. These rules will look at SQL and will do the necessary transformation. But if the rule can't transform the query, it returns back the control to the calcite planner without recording why was it not able to transform. E.g. there is a join query with a non-equal join condition. DruidJoinRule will look at the condition, see that it is not supported, and return back the control. The reason can be that a query can be planned in many different ways so if one rule can't parse it, the query may still be parseable by other rules. In this PR, we are intercepting these gaps and passing them back to the user if the query could not be planned at all.

2. The said capability has been used to generate actionable errors for some common unsupported SQL features. However, not all possible errors are covered and we can keep adding more in the future.

Better serverView exec name; remove SingleServerInventoryView (#11770)
Druid currently has 2 serverViews, regular serverView and filtered serverView. The regular serverView is used to monitor all segment announcements from all data nodes (historicals, tasks, indexers). The filtered serverView is used when you want to watch segment announcements from particular tiers. Since these server views keep track of different sets of druidServers and segments in memory, they should be maintained separately. However, they currently share the same name for their executorService, which can cause confusion and make debugging harder especially in the broker since it is using both serverViews, the filtered view for normal query processing and the regular view to serve the servers table (I'm unsure whether this is intended or whether this is a good behavior). This PR changes it to a more obvious name.

This PR also removes SingleServerInventoryView. This view was deprecated a long time ago and has not been documented at least since 0.13 (#6127). I also don't think this can be better in any case than BatchServerInventoryView. Finally, I merged AbstractCuratorServerInventoryView and BatchServerInventoryView as we no longer need AbstractCuratorServerInventoryView after SingleServerInventoryView is removed.

1) Ability to use handlers other than StringFullResponseHandler. This

   we'll be able to use this to make task-to-task communication
   more efficient.

2) Truncate server errors at 1KB, so long errors do not pollute logs.

3) Change error log level for retryable errors from WARN to INFO. (The
   final error is still WARN.)

4) Harmonize log and exception messages to have a more consistent format.

Consolidate a bunch of ad-hoc segments metadata SQL; fix some bugs. (#11582)
* Consolidate a bunch of ad-hoc segments metadata SQL; fix some bugs.

This patch gathers together a variety of SQL from SqlSegmentsMetadataManager
and IndexerSQLMetadataStorageCoordinator into a new class SqlSegmentsMetadataQuery.
It focuses on SQL related to retrieving segment payloads and marking
segments used and unused.

In addition to cleaning up the code a bit, this patch also fixes a bug
with years before 0 or after 9999. The prior SQL did not work properly
because dates outside this range cannot be compared as strings. The new
code does work for these far-past and far-future years.

So, if you're ever interested in using Druid to analyze things from
ancient Babylon, you better apply this patch first!

* Fix test compiling.

* Fixes and improvements.

* Fix forbidden API.

Harmonize local input sources; fix batch index integration test. (#11965)
* Make LocalInputSource.files a List instead of Set and adjust wikipedia_index_task to use file list.

Rationale: the behavior of wikipedia_index_task.json is order-dependent with regard to its input
files; some orders produce 4 segments and some produce 5 segments. Some integration tests, like
ITSystemTableBatchIndexTaskTest and ITAutoCompactionTest, are written assuming that the
4-segment case will always happen. Providing the file list in a specific order ensures that this
will happen as expected by the tests.

I didn't see a specific reason why the LocalInputSource.files parameter needed to be a Set, so
changing it to a List was the simplest way to achieve the consistent ordering. I think it will
also make the behavior make more sense if someone does specify the same input file multiple
times in a spec: I think they'd expect it to be loaded multiple times instead of deduped. This
is consistent with the behavior of other input sources like S3, GCS, HTTP.

* Sort files in LocalFirehoseFactory.

Use a simple class to sanitize JDBC exceptions and also log them (#11843)
* Use a simple class to sanitize sanitizable errors and log them

The purpose of this is to sanitize JDBC errors, but can sanitize other errors
if they implement SanitizableError Interface

add a class to log errors and sanitize them
added a simple test that tests out that the error gets sanitized
add @NonNull annotation to serverconfig's ErrorResponseTransfromStrategy

* return less information as part of too many connections, and instead only log specific details

This is so an end user gets relevant information but not too much info since they might now how
many brokers they have

* return only runtime exceptions

added new error types that need to be sanitized
also sanitize deprecated and unsupported exceptions.

* dont reqrewite exceptions unless necessary for checked exceptions

add docs
avoid blanket turning all exceptions into runtime exceptions

* address comments, to fix up docs.

add more javadocs
add support UOE sanitization

* use try catch instead and sanitize at public methods

* checkstyle fixes

* throw noSuchStatement and NoSuchConnection as Avatica is affected by those

* address comments. move log error back to druid meta

clean up bad formatting and commented code. add missed catch for NoSuchStatementException
clean up comments for error handler and add comment explainging not wanting to santize avatica exceptions

* alter test to reflect new error message

Make subquery IDs more comprehensive (#11809)
There are 3 types of query IDs - id, subQueryId, sqlQueryId. Currently, whenever a query generates subqueries, the subquery's subQueryId is populated randomly. Also, subquery's Id is not set to the parent query Id. Therefore there is no way of linking the subqueries to the parent query, and one loses the ability to look at end to end view of the query.

This PR aims to implement following couple of things:

Populate the subqueries with it's parent's id (and sqlQueryId if present)
Populate the subqueryId such that it forms a hierarchical relationship amongs themselves. For example, if there is a query which launches a subquery, which in turn launches a couple of subqueries, then the ids and subQueryIds should have following structure.

RowBasedSegment: Use Sequence instead of Iterable. (#11886)
* RowBasedSegment: Use Sequence instead of Iterable.

The main reason this is good is that Sequences can include baggage that
must be closed after iteration is finished. This enables creating
RowBasedSegments on top of closeable sequences of rows.

To preserve the optimization that allows reversing a List without
copying it, this patch also makes SimpleSequence its own class and allows
extracting the Iterable that was used to create it.

Add support for multi dimension range partitioning (#11848)
This PR adds support for range partitioning on multiple dimensions. It extends on the
concept and implementation of single dimension range partitioning.

The new partition type added is range which corresponds to a set of Dimension Range Partition classes. single_dim is now treated as a range type partition with a single partition dimension.

The start and end values of a DimensionRangeShardSpec are represented
by StringTuples, where each String in the tuple is the value of a partition dimension.

Remove CloseQuietly and migrate its usages to other methods. (#10247)
* Remove CloseQuietly and migrate its usages to other methods.

These other methods include:

1) New method CloseableUtils.closeAndWrapExceptions, which wraps IOExceptions
   in RuntimeExceptions for callers that just want to avoid dealing with
   checked exceptions. Most usages were migrated to this method, because it
   looks like they were mainly attempts to avoid declaring a throws clause,
   and perhaps were unintentionally suppressing IOExceptions.
2) New method CloseableUtils.closeInCatch, designed to properly close something
   in a catch block without losing exceptions. Some usages from catch blocks
   were migrated here, when it seemed that they were intended to avoid checked
   exception handling, and did not really intend to also suppress IOExceptions.
3) New method CloseableUtils.closeAndSuppressExceptions, which sends all
   exceptions to a "chomper" that consumes them. Nothing is thrown or returned.
   The behavior is slightly different: with this method, _all_ exceptions are
   suppressed, not just IOExceptions. Calls that seemed like they had good
   reason to suppress exceptions were migrated here.
4) Some calls were migrated to try-with-resources, in cases where it appeared
   that CloseQuietly was being used to avoid throwing an exception in a finally
   block.

Add Broker config `druid.broker.segment.ignoredTiers` (#11766)
The new config is an extension of the concept of "watchedTiers" where
the Broker can choose to add the info of only the specified tiers to its timeline.
Similarly, with this config, Broker can choose to ignore the segments being served
by the specified historical tiers. By default, no tier is ignored.

This config is useful when you want a completely isolated tier amongst many other tiers.

Say there are several tiers of historicals Tier T1, Tier T2 ... Tier Tn
and there are several brokers Broker B1, Broker B2 .... Broker Bm

If we want only Broker B1 to query Tier T1, instead of setting a long list of watchedTiers
on each of the other Brokers B2 ... Bm, we could just set druid.broker.segment.ignoredTiers=["T1"]
for these Brokers, while Broker B1 could have druid.broker.segment.watchedTiers=["T1"]

Update the default maxSegmentsInNodeLoadingQueue from 0 (unbounded) to 100.

An unbounded maxSegmentsInNodeLoadingQueue can cause cluster instability.
Since this is the default druid operators need to run into this instability
and then look through the docs to see that the recommended value for a large
cluster is 1000. This change makes it so the default will prevent clusters
from falling over as they grow over time.

This change allows the selection of a specific broker service (or broker tier) by the Router.

The newly added ManualTieredBrokerSelectorStrategy works as follows:

Check for the parameter brokerService in the query context. If this is a valid broker service, use it.
Check if the field defaultManualBrokerService has been set in the strategy. If this is a valid broker service, use it.
Move on to the next strategy

Make SegmentLoader extensible and customizable (#11398)
This PR refactors the code related to segment loading specifically SegmentLoader and SegmentLoaderLocalCacheManager. SegmentLoader is marked UnstableAPI which means, it can be extended outside core druid in custom extensions. Here is a summary of changes

SegmentLoader returns an instance of ReferenceCountingSegment instead of Segment. Earlier, SegmentManager was wrapping Segment objects inside ReferenceCountingSegment. That is now moved to SegmentLoader. With this, a custom implementation can track the references of segments. It also allows them to create custom ReferenceCountingSegment implementations. For this reason, the constructor visibility in ReferenceCountingSegment is changed from private to protected.
SegmentCacheManager has two additional methods called - reserve(DataSegment) and release(DataSegment). These methods let the caller reserve or release space without calling SegmentLoader#getSegment. We already had similar methods in StorageLocation and now they are available in SegmentCacheManager too which wraps multiple locations.
Refactoring to simplify the code in SegmentCacheManager wherever possible. There is no change in the functionality.

Split SegmentLoader into SegmentLoader and SegmentCacheManager (#11466)
This PR splits current SegmentLoader into SegmentLoader and SegmentCacheManager.

SegmentLoader - this class is responsible for building the segment object but does not expose any methods for downloading, cache space management, etc. Default implementation delegates the download operations to SegmentCacheManager and only contains the logic for building segments once downloaded. . This class will be used in SegmentManager to construct Segment objects.

SegmentCacheManager - this class manages the segment cache on the local disk. It fetches the segment files to the local disk, can clean up the cache, and in the future, support reserve and release on cache space. [See https://github.com/Make SegmentLoader extensible and customizable #11398]. This class will be used in ingestion tasks such as compaction, re-indexing where segment files need to be downloaded locally.

Replace Processing ExecutorService with QueryProcessingPool (#11382)
This PR refactors the code for QueryRunnerFactory#mergeRunners to accept a new interface called QueryProcessingPool instead of ExecutorService for concurrent execution of query runners. This interface will let custom extensions inject their own implementation for deciding which query-runner to prioritize first. The default implementation is the same as today that takes the priority of query into account. QueryProcessingPool can also be used as a regular executor service. It has a dedicated method for accepting query execution work so implementations can differentiate between regular async tasks and query execution tasks. This dedicated method also passes the QueryRunner object as part of the task information. This hook will let custom extensions carry any state from QuerySegmentWalker to QueryProcessingPool#mergeRunners which is not possible currently.

remove ZooKeeper 3.4 support + pass tests with Java 15 (#11073)
With this change, Druid will only support ZooKeeper 3.5.x and later.

In order to support Java 15 we need to switch to ZK 3.5.x client libraries and drop support for ZK 3.4.x
(see #10780 for the detailed reasons) 

* remove ZooKeeper 3.4.x compatibility
* exclude additional ZK 3.5.x netty dependencies to ensure we use our version
* keep ZooKeeper version used for integration tests in sync with client library version
* remove the need to specify ZK version at runtime for docker
* add support to run integration tests with JDK 15
* build and run unit tests with Java 15 in travis

Add paramter to loadstatus API to compute underdeplication against cluster view (#11056)
* Add paramter to loadstatus API to compute underdeplication against cluster view

This change adds a query parameter `computeUsingClusterView` to loadstatus apis
that if specified have the coordinator compute undereplication for segments based
on the number of services available within cluster that the segment can be replicated
on, instead of the configured replication count configured in load rule. A default
load rule is created in all clusters that specified that all segments should be
replicated 2 times. As replicas are forced to be on separate nodes in the cluster,
this causes the loadstatus api to report that there are under-replicated segments
when there is only 1 data server in the cluster. In this case, calling loadstatus
api without this new query parameter will always result in a response indicating
under-replication of segments

DruidInputSource: Fix issues in column projection, timestamp handling. (#10267)
* DruidInputSource: Fix issues in column projection, timestamp handling.

DruidInputSource, DruidSegmentReader changes:

1) Remove "dimensions" and "metrics". They are not necessary, because we
   can compute which columns we need to read based on what is going to
   be used by the timestamp, transform, dimensions, and metrics.
2) Start using ColumnsFilter (see below) to decide which columns we need
   to read.
3) Actually respect the "timestampSpec". Previously, it was ignored, and
   the timestamp of the returned InputRows was set to the `__time` column
   of the input datasource.

(1) and (2) together fix a bug in which the DruidInputSource would not
properly read columns that are used as inputs to a transformSpec.

(3) fixes a bug where the timestampSpec would be ignored if you attempted
to set the column to something other than `__time`.

(1) and (3) are breaking changes.

Web console changes:

1) Remove "Dimensions" and "Metrics" from the Druid input source.
2) Set timestampSpec to `{"column": "__time", "format": "millis"}` for
   compatibility with the new behavior.

Other changes:

1) Add ColumnsFilter, a new class that allows input readers to determine
   which columns they need to read. Currently, it's only used by the
   DruidInputSource, but it could be used by other columnar input sources
   in the future.
2) Add a ColumnsFilter to InputRowSchema.
3) Remove the metric names from InputRowSchema (they were unused).
4) Add InputRowSchemas.fromDataSchema method that computes the proper
   ColumnsFilter for given timestamp, dimensions, transform, and metrics.
5) Add "getRequiredColumns" method to TransformSpec to support the above.
