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.
* Enable allocating segments at ALL granularity.
The main change is that Granularity.granularitiesFinerThan will return ALL if ALL
is passed in.
Allocating segments at ALL granularity is somewhat unconventional, but there
is nothing wrong with it, and it actually makes a lot of sense for tables that
are meant to be used for lookups or dimensions rather than main fact tables.
This change enables ALL segmentGranularity to work properly in appendToExisting
mode.
Also clarifies behavior in javadocs and tests.
* Move tests to improve coverage.
* Enhancements to IndexTaskClient.
1) Ability to use handlers other than StringFullResponseHandler. This
functionality is not used in production code yet, but is useful
because it will allow tasks to communicate with each other in
non-string-based formats and in streaming fashion. In the future,
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.
* Additional tests and improvements.
changes:
* adds new config, druid.expressions.useStrictBooleans which make longs the official boolean type of all expressions
* vectorize logical operators and boolean functions, some only if useStrictBooleans is true
* Code cleanup from query profile project
* Fix spelling errors
* Fix Javadoc formatting
* Abstract out repeated test code
* Reuse constants in place of some string literals
* Fix up some parameterized types
* Reduce warnings reported by Eclipse
* Reverted change due to lack of tests
* Add support for custom reset condition & support for other args to have defaults to make the method api consistent
* Add support for custom reset condition to InputEntity
* Fix test names
* Clarifying comments to why we need to read the message's content to identify S3's resettable exception
* Add unit test to verify custom resettable condition for S3Entity
* Provide a way to customize retries since they are expensive to test
* 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.
* Additional fixes.
* SQL INSERT planner support.
The main changes are:
1) DruidPlanner is able to validate and authorize INSERT queries. They
require WRITE permission on the target datasource.
2) QueryMaker is now an interface, and there is a QueryMakerFactory that
creates instances of it. There is only one production implementation
of each (NativeQueryMaker and NativeQueryMakerFactory), which
together behave the same way as the former QueryMaker class. But this
opens the door to executing queries in ways other than the Druid
query stack, and is used by unit tests (CalciteInsertDmlTest) to
test the INSERT planning functionality.
3) Adds an EXTERN table macro that allows references external data using
InputSource and InputFormat from Druid's batch ingestion API. This is
not exposed in production yet, but is used by unit tests.
4) Adds a QueryFeature concept that enables the planner to change its
behavior slightly depending on the capabilities of the execution
system.
5) Adds an "AuthorizableOperator" concept that enables SqlOperators
to require additional permissions. This is used by the EXTERN table
macro.
Related odds and ends:
- Add equals, hashCode, toString methods to InlineInputSource. Aids in
the "from external" tests in CalciteInsertDmlTest.
- Add JSON-serializability to RowSignature.
- Move the SQL string inside PlannerContext so it is "baked into" the
planner when the planner is created. Cleans up the code a bit, since
in practice, the same query is passed in every time to the
same planner anyway.
* Fix up calls to CalciteTests.createMockQueryLifecycleFactory.
* Fix checkstyle issues.
* Adjustments for CI.
* Adjust DruidAvaticaHandlerTest for stricter test authorizations.

Update the javadoc on LifecycleModule to be more clear about why the register methods exist and why they should always be used instead of Guice's eager instantiation.
* 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.

* 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

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

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
Add method ShardSpec.getType() to get name of shard spec type
List all names of shard spec types in the interface ShardSpec itself
for easy reference and maintenance
Add dimension partitioningType to metric segment/added/bytes
* 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.
* Fix tests.
This PR has changes to ensure backward compatibility of multi dimension partitioning
such that if some middle managers are upgraded to a newer version, the cluster still
functions normally for single_dim use cases.
* Support routing data through an HTTP proxy
* Support routing data through an HTTP proxy
This adds the ability for the HttpClient to connect through an HTTP proxy. We
augment the channel factory to check if it is supposed to be proxied and, if so,
we connect to the proxy host first, issue a CONNECT command through to the final
recipient host and *then* give the channel to the normal http client for usage.
* add docs
* address comments

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.
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.

ProcCgroupDiscoverer builds the cgroup directory by concatenating the proc mounts and proc cgroup paths together. This doesn't seem to work in Kubernetes if the execution context is within the container. Also this isn't consistent across all Linux OSes. The fix is to fallback to / as the root and it seems to work empirically.

* InDimFilter: Fix NPE involving certain Set types.
Normally, InDimFilters that come from JSON have HashSets for "values".
However, programmatically-generated filters (like the ones from #11068)
may use other set types. Some set types, like TreeSets with natural
ordering, will throw NPE on "contains(null)", which causes the
InDimFilter's ValueMatcher to throw NPE if it encounters a null value.
This patch adds code to detect if the values set can support
contains(null), and if not, wrap that in a null-checking lambda.
Also included:
- Remove unneeded NullHandling.needsEmptyToNull method.
- Update IndexedTableJoinable to generate a TreeSet that does not
require lambda-wrapping. (This particular TreeSet is how I noticed
the bug in the first place.)

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.
