Allow users to pass task payload via deep storage instead of environment variable (#14887)
This change is meant to fix a issue where passing too large of a task payload to the mm-less task runner will cause the peon to fail to startup because the payload is passed (compressed) as a environment variable (TASK_JSON). In linux systems the limit for a environment variable is commonly 128KB, for windows systems less than this. Setting a env variable longer than this results in a bunch of "Argument list too long" errors.

Support getTaskLocation for mixed task runner (#15033)
The KubernetesAndWorkerTaskRunner currently doesn't implement getTaskLocation, so tasks run by it will show a unknown TaskLocation in the druid console after a task has completed.

Fix bug in KubernetesAndWorkerTaskRunner that manifests as missing information in the druid Web Console.

Upgrade guava version to 31.1-jre (#14767)
Currently, Druid is using Guava 16.0.1 version. This upgrade to 31.1-jre fixes the following issues.

CVE-2018-10237 (Unbounded memory allocation in Google Guava 11.0 through 24.x before 24.1.1 allows remote attackers to conduct denial of service attacks against servers that depend on this library and deserialize attacker-provided data because the AtomicDoubleArray class (when serialized with Java serialization) and the CompoundOrdering class (when serialized with GWT serialization) perform eager allocation without appropriate checks on what a client has sent and whether the data size is reasonable). We don't use Java or GWT serializations. Despite being false positive they're causing red security scans on Druid distribution.
Latest version of google-client-api is incompatible with the existing Guava version. This PR unblocks Update google client apis to latest version #14414

Add sampling factor for DeterminePartitionsJob (#13840)
There are two type of DeterminePartitionsJob:
-  When the input data is not assume grouped, there may be duplicate rows.
In this case, two MR jobs are launched. The first one do group job to remove duplicate rows.
And a second one to perform global sorting to find lower and upper bound for target segments.
- When the input data is assume grouped, we only need to launch the global sorting
MR job to find lower and upper bound for segments.

Sampling strategy:
- If the input data is assume grouped, sample by random at the mapper side of the global sort mr job.
- If the input data is not assume grouped, sample at the mapper of the group job. Use hash on time
and all dimensions and mod by sampling factor to sample, don't use random method because there
may be duplicate rows.

Minimize PostAggregator computations (#14708)
* Minimize PostAggregator computations

Since a change back in 2014, the topN query has been computing
all PostAggregators on all intermediate responses from leaf nodes
to brokers.  This generates significant slow downs for queries
with relatively expensive PostAggregators.  This change rewrites
the query that is pushed down to only have the minimal set of
PostAggregators such that it is impossible for downstream
processing to do too much work.  The final PostAggregators are
applied at the very end.

Extension to read and ingest iceberg data files (#14329)
This adds a new contrib extension: druid-iceberg-extensions which can be used to ingest data stored in Apache Iceberg format. It adds a new input source of type iceberg that connects to a catalog and retrieves the data files associated with an iceberg table and provides these data file paths to either an S3 or HDFS input source depending on the warehouse location.

Two important dependencies associated with Apache Iceberg tables are:

Catalog : This extension supports reading from either a Hive Metastore catalog or a Local file-based catalog. Support for AWS Glue is not available yet.
Warehouse : This extension supports reading data files from either HDFS or S3. Adapters for other cloud object locations should be easy to add by extending the AbstractInputSourceAdapter.

Be able to load segments on Peons (#14239)
* Be able to load segments on Peons

This change introduces a new config on WorkerConfig
that indicates how many bytes of each storage
location to use for storage of a task.  Said config
is divided up amongst the locations and slots
and then used to set TaskConfig.tmpStorageBytesPerTask

The Peons use their local task dir and
tmpStorageBytesPerTask as their StorageLocations for
the SegmentManager such that they can accept broadcast
segments.

fix bugs with auto encoded long vector deserializers (#14186)
This PR fixes an issue when using 'auto' encoded LONG typed columns and the 'vectorized' query engine. These columns use a delta based bit-packing mechanism, and errors in the vectorized reader would cause it to incorrectly read column values for some bit sizes (1 through 32 bits). This is a regression caused by #11004, which added the optimized readers to improve performance, so impacts Druid versions 0.22.0+.

While writing the test I finally got sad enough about IndexSpec not having a "builder", so I made one, and switched all the things to use it. Apologies for the noise in this bug fix PR, the only real changes are in VSizeLongSerde, and the tests that have been modified to cover the buggy behavior, VSizeLongSerdeTest and ExpressionVectorSelectorsTest. Everything else is just cleanup of IndexSpec usage.

Update Hadoop3 as default build version (#14005)
Hadoop 2 often causes red security scans on Druid distribution because of the dependencies it brings. We want to move away from Hadoop 2 and provide Hadoop 3 distribution available. Switch druid to building with Hadoop 3 by default. Druid will still be compatible with Hadoop 2 and users can build hadoop-2 compatible distribution using hadoop2 profile.

Make the tasks run with only a single directory (#14063)
* Make the tasks run with only a single directory

There was a change that tried to get indexing to run on multiple disks
It made a bunch of changes to how tasks run, effectively hiding the
"safe" directory for tasks to write files into from the task code itself
making it extremely difficult to do anything correctly inside of a task.

This change reverts those changes inside of the tasks and makes it so that
only the task runners are the ones that make decisions about which
mount points should be used for storing task-related files.

It adds the config druid.worker.baseTaskDirs which can be used by the
task runners to know which directories they should schedule tasks inside of.
The TaskConfig remains the authoritative source of configuration for where
and how an individual task should be operating.

Always use file sizes when determining batch ingest splits (#13955)
* Always use file sizes when determining batch ingest splits.

Main changes:

1) Update CloudObjectInputSource and its subclasses (S3, GCS,
   Azure, Aliyun OSS) to use SplitHintSpecs in all cases. Previously, they
   were only used for prefixes, not uris or objects.

2) Update ExternalInputSpecSlicer (MSQ) to consider file size. Previously,
   file size was ignored; all files were treated as equal weight when
   determining splits.

A side effect of these changes is that we'll make additional network
calls to find the sizes of objects when users specify URIs or objects
as opposed to prefixes. IMO, this is worth it because it's the only way
to respect the user's split hint and task assignment settings.

Secondary changes:

1) S3, Aliyun OSS: Use getObjectMetadata instead of listObjects to get
   metadata for a single object. This is a simpler call that is also
   expected to be less expensive.

2) Azure: Fix a bug where getBlobLength did not populate blob
   reference attributes, and therefore would not actually retrieve the
   blob length.

3) MSQ: Align dynamic slicing logic between ExternalInputSpecSlicer and
   TableInputSpecSlicer.

4) MSQ: Adjust WorkerInputs to ensure there is always at least one
   worker, even if it has a nil slice.

Fix bug in k8s task runner in handling deleted jobs (#14001)
With the KubernetesTaskRunner, if a task is manually shutdown via the web console while running or the corresponding k8s job is manually deleted, the thread responsible for overseeing the task gets stuck in a loop because the fabric8 client sends one event to it that the job is null when the job is deleted, but this doesn't pass the condition.

This means that the thread is stuck waiting on a fabric8 event (the job being successful) that will never come up until maxTaskDuration (default 4 hours). If a user of the extension is trying to use a limited taskqueue maxSize, this can cause problems as the k8s executor pool is unable to pick up additional tasks (since threads are stuck waiting on the old tasks that have already been deleted).

Removes FiniteFirehoseFactory and its implementations (#12852)
The FiniteFirehoseFactory and InputRowParser classes were deprecated in 0.17.0 (#8823) in favor of InputSource & InputFormat. This PR removes the FiniteFirehoseFactory and all its implementations along with classes solely used by them like Fetcher (Used by PrefetchableTextFilesFirehoseFactory). Refactors classes including tests using FiniteFirehoseFactory to use InputSource instead.
Removing InputRowParser may not be as trivial as many classes that aren't deprecated depends on it (with no alternatives), like EventReceiverFirehoseFactory. Hence FirehoseFactory, EventReceiverFirehoseFactory, and Firehose are marked deprecated.

various nested column (and other) fixes (#13732)
changes:
* modified druid schema column type compution to special case COMPLEX<json> handling to choose COMPLEX<json> if any column in any segment is COMPLEX<json>
* NestedFieldVirtualColumn can now work correctly on any type of column, returning either a column selector if a root path, or nil selector if not
* fixed a random bug with NilVectorSelector when using a vector size larger than the default and druid.generic.useDefaultValueForNull=false would have the nulls vector set to all false instead of true
* fixed an overly aggressive check in ExprEval.ofType when handling complex types which would try to treat any string as base64 without gracefully falling back if it was not in fact base64 encoded, along with special handling for complex<json>
* added ExpressionVectorSelectors.castValueSelectorToObject and ExpressionVectorSelectors.castObjectSelectorToNumeric as convience methods to cast vector selectors using cast expressions without the trouble of constructing an expression. the polymorphic nature of the non-vectorized engine (and significantly larger overhead of non-vectorized expression processing) made adding similar methods for non-vectorized selectors less attractive and so have not been added at this time
* fix inconsistency between nested column indexer and serializer in handling values (coerce non primitive and non arrays of primitives using asString)
* ExprEval best effort mode now handles byte[] as string
* added test for ExprEval.bestEffortOf, and add missing conversion cases that tests uncovered
* more tests more better

Add InputStats to track bytes processed by a task (#13520)
This commit adds a new class `InputStats` to track the total bytes processed by a task.
The field `processedBytes` is published in task reports along with other row stats.

Major changes:
- Add class `InputStats` to track processed bytes
- Add method `InputSourceReader.read(InputStats)` to read input rows while counting bytes.
> Since we need to count the bytes, we could not just have a wrapper around `InputSourceReader` or `InputEntityReader` (the way `CountableInputSourceReader` does) because the `InputSourceReader` only deals with `InputRow`s and the byte information is already lost.
- Classic batch: Use the new `InputSourceReader.read(inputStats)` in `AbstractBatchIndexTask`
- Streaming: Increment `processedBytes` in `StreamChunkParser`. This does not use the new `InputSourceReader.read(inputStats)` method.
- Extend `InputStats` with `RowIngestionMeters` so that bytes can be exposed in task reports

Other changes:
- Update tests to verify the value of `processedBytes`
- Rename `MutableRowIngestionMeters` to `SimpleRowIngestionMeters` and remove duplicate class
- Replace `CacheTestSegmentCacheManager` with `NoopSegmentCacheManager`
- Refactor `KafkaIndexTaskTest` and `KinesisIndexTaskTest`

SQL: Use timestamp_floor when granularity is not safe. (#13206)
* SQL: Use timestamp_floor when granularity is not safe.

PR #12944 added a check at the execution layer to avoid materializing
excessive amounts of time-granular buckets. This patch modifies the SQL
planner to avoid generating queries that would throw such errors, by
switching certain plans to use the timestamp_floor function instead of
granularities. This applies both to the Timeseries query type, and the
GroupBy timestampResultFieldGranularity feature.

The patch also goes one step further: we switch to timestamp_floor
not just in the ETERNITY + non-ALL case, but also if the estimated
number of time-granular buckets exceeds 100,000.

Finally, the patch modifies the timestampResultFieldGranularity
field to consistently be a String rather than a Granularity. This
ensures that it can be round-trip serialized and deserialized, which is
useful when trying to execute the results of "EXPLAIN PLAN FOR" with
GroupBy queries that use the timestampResultFieldGranularity feature.

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:

Improve global-cached-lookups metric reporting (#13219)
It was found that the namespace/cache/heapSizeInBytes metric that tracks the total heap size in bytes of all lookup caches loaded on a service instance was being under reported. We were not accounting for the memory overhead of the String object, which I've found in testing to be ~40 bytes. While this overhead may be java version dependent, it should not vary much, and accounting for this provides a better estimate. Also fixed some logging, and reading bytes from the JDBI result set a little more efficient by saving hash table lookups. Also added some of the lookup metrics to the default statsD emitter metric whitelist.

implementations).

It also includes various bug fixes and cleanup to the original
CompressedBigDecimal code include the AggregatorFactories. Various null
handling was improved.

Additional test cases were added for both new and existing code
including a base test case for AggregationFactories. Other tests common
across sum,min,max may be refactored also to share the varoius cases in
the future.

Add BIG_SUM SQL function (#13102)
This adds a sql function, "BIG_SUM", that uses
CompressedBigDecimal to do a sum. Other misc changes:

1. handle NumberFormatExceptions when parsing a string (default to set
   to 0, configurable in agg factory to be strict and throw on error)
2. format pom file (whitespace) + add dependency
3. scaleUp -> scale and always require scale as a parameter

compressed big decimal - module (#10705)
Compressed Big Decimal is an extension which provides support for 
Mutable big decimal value that can be used to accumulate values 
without losing precision or reallocating memory. This type helps in 
absolute precision arithmetic on large numbers in applications, 
where greater level of accuracy is required, such as financial 
applications, currency based transactions. This helps avoid rounding 
issues where in potentially large amount of money can be lost.

Accumulation requires that the two numbers have the same scale, 
but does not require that they are of the same size. If the value 
being accumulated has a larger underlying array than this value 
(the result), then the higher order bits are dropped, similar to what 
happens when adding a long to an int and storing the result in an 
int. A compressed big decimal that holds its data with an embedded 
array.

Compressed big decimal is an absolute number based complex type 
based on big decimal in Java. This supports all the functionalities 
supported by Java Big Decimal. Java Big Decimal is not mutable in 
order to avoid big garbage collection issues. Compressed big decimal 
is needed to mutate the value in the accumulator.

#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.

Able to filter Cloud objects with glob notation. (#12659)
In a heterogeneous environment, sometimes you don't have control over the input folder. Upstream can put any folder they want. In this situation the S3InputSource.java is unusable.

Most people like me solved it by using Airflow to fetch the full list of parquet files and pass it over to Druid. But doing this explodes the JSON spec. We had a situation where 1 of the JSON spec is 16MB and that's simply too much for Overlord.

This patch allows users to pass {"filter": "*.parquet"} and let Druid performs the filtering of the input files.

I am using the glob notation to be consistent with the LocalFirehose syntax.

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.

Add remedial information in error message when type is unknown (#12612)
Often users are submitting queries, and ingestion specs that work only if the relevant extension is not loaded. However, the error is too technical for the users and doesn't suggest them to check for missing extensions. This PR modifies the error message so users can at least check their settings before assuming that the error is because of a bug.

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."

This reverts commit 49f846d9e3.

* Add TestBufferPool.

* Revert Xmx change in tests.

* Better behaved NestedQueryPushDownTest. Exit tests on OOME.

* Remove T1C from ARM tests.

* Somewhat safer.

* Fix style stuff.

* Additional debugging.

* Reset null / expr configs better.

* ExpressionLambdaAggregatorFactory thread-safety.

* Alter forkNode to try to get better info when a JVM crashes.

* Fix buffer retention in ExpressionLambdaAggregatorFactory.

* Remove unused import.

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.
