* MSQ: Controller checker should check for "closed" only.
Currently, the worker's controller checker will exit the worker if
the controller location is "closed" (no longer running) or if its location
is empty (i.e. location unknown).
This patch changes to only exit on "closed". We shouldn't exit on empty
location, because that may happen if the Overlord is slow to acknowledge the
location of a task.
* Fix test.
* SortMerge join support for IS NOT DISTINCT FROM.
The patch adds a "requiredNonNullKeyParts" field to the sortMerge
processor, which has the list of key parts that must be nonnull for
an equijoin condition to match. Conditions with SQL "=" are present in
the list; conditions with SQL "IS NOT DISTINCT FROM" are absent from
the list.
* Fix test.
* Update javadoc.
* Mark used and unused APIs by versions.

TaskTracker's status is null when TaskTrackers are first set up, and
stay null until the first status call comes back. This patch handles
that case and sets the status code to null in the WorkerStats object
in live reports.
Prior to this patch, when canceled, workers would keep trying to contact
the controller: they would attempt to report an error, and if they were
in the midst of some other call (like a counters push) they would keep
trying it.
This can cause cancellation to be delayed, because the controller shuts
down its HTTP server before it cancels workers. Workers are then stuck
retrying calls to the controller that will never succeed. The retry loops
are broken when the controller gives up on them (one minute later) and
exits for real. Then, the controller failure detection logic on the worker
detects that the controller has failed, and the worker finally shuts down.
This patch speeds up worker cancellation by bypassing communication
with the controller. There is no real need for it. If the controller
canceled the workers, it isn't interested in further communications from
them. If the workers were canceled out-of-band, the controller can
detect this through worker monitoring and report it as a WorkerFailed
error.
* Add update() in TestDerbyConnectorRule
* use common function.
* fixup build.
* fixup indentations.
* Revert "fixup indentations."
This reverts commit a9d6b73e79.
* fixup indentataions.
* Remove Thread.sleep() by directly calling updateUsedStatusLastUpdated.
* another indentation slip.
* Move common segment initialization to setup().
* Fix for checkstyle.
* review comments: indentation fixes, type.
* Wrapper class for Segments table
* Add KillUnusedSegmentsTaskBuilder in test class
* Remove javadocs for self-explanatory methods.
Changes:
- Remove deprecated `DruidException` (old one) and `EntryExistsException`
- Use newly added comprehensive `DruidException` instead
- Update error message in `SqlMetadataStorageActionHandler` when max packet limit is violated.
- Factor out common code from several faults into `BaseFault`.
- Slightly update javadoc in `DruidException` to render it correctly
- Remove unused classes `SegmentToMove`, `SegmentToDrop`
- Move `ServletResourceUtils` from module `druid-processing` to `druid-server`
- Add utility method to build error Response from `DruidException`.
changes:
* fix issues with array_contains and array_overlap with null left side arguments
* modify singleThreaded stuff to allow optimizing Function similar to how we do for ExprMacro - removed SingleThreadSpecializable in favor of default impl of asSingleThreaded on Expr with clear javadocs that most callers shouldn't be calling it directly and should be using Expr.singleThreaded static method which uses a shuttle and delegates to asSingleThreaded instead
* add optimized 'singleThreaded' versions of array_contains and array_overlap
* add mv_harmonize_nulls native expression to use with MV_CONTAINS and MV_OVERLAP to allow them to behave consistently with filter rewrites, coercing null and [] into [null]
* fix bug with casting rhs argument for native array_contains and array_overlap expressions
* MSQ: Validate that strings and string arrays are not mixed.
When multi-value strings and string arrays coexist in the same column,
it causes problems with "classic MVD" style queries such as:
select * from wikipedia -- fails at runtime
select count(*) from wikipedia where flags = 'B' -- fails at planning time
select flags, count(*) from wikipedia group by 1 -- fails at runtime
To avoid these problems, this patch adds type verification for INSERT
and REPLACE. It is targeted: the only type changes that are blocked are
string-to-array and array-to-string. There is also a way to exclude
certain columns from the type checks, if the user really knows what
they're doing.

* MSQ: Plan without implicit sorting.
This patch adds an EngineFeature "GROUPBY_IMPLICITLY_SORTS" and sets
it true for native, false for MSQ. It's useful for two reasons:
1) In the future we'll likely want MSQ to hash-partition for GROUP BY
instead of using a global sort, which would mean MSQ would not
implicitly ORDER BY when there is a GROUP BY.
2) When doing REPLACE with MSQ, CLUSTERED BY is transformed to ORDER BY.
We should retain that ORDER BY, as it may be a subset of the GROUP BY,
and it is important to remember which fields the user wanted to include in
range shard specs.
* Fix tests.
* Fix tests for real.
* Fix test.
ConcurrentGrouper kind of misuses ThreadLocal to hold a SpillingGrouper, and never calls remove() on it, which can result in large amounts of heap being retained as weak references even after grouping is finished. This PR calls keySerde.reset() on all of the Grouper.close() implementations that have a KeySerde and should free up a bunch of space that is no longer needed.
Changes
- Replace usages of `UnknownSegmentIdsException` with `DruidException`
- Add method `SqlMetadataQuery.retrieveSegments`
- Add new field `used` to `DataSegmentPlus`
* Kill task version support.
Kill tasks by default kill all versions of unused segments in the specified
interval. Users wanting to delete specific versions (for example, data compliance
reasons) and keep rest of the versions can specify the optional version in the
kill task payload.
* Formatting changes.
* Multi version tests in RetrieveSegmentsActionsTest
Sort of like method-level parameterized tests.
* Address review feedback
* Accept a list of versions instead of a single version.
Support multiple versions.
* Tests for multiple versions.
* Update docs
* Cleanup
* Address review comments.
Retain the old interface method and make it default and route it to
the method with nullable versions variant. Update usages to use the
default method where versions doesn't matter.
* Remove versions from retreive used segments action.
* Some updates.
* Apply suggestions from code review

Handling array with boolean literals like ARRAY[true, false]
Druid appears to be able to convert an array with boolean expressions like this array[added=deleted, added=delta] into a numeric array of 0 and 1: select array[added=deleted, added=delta] from wikipedia
However, select array[true, false] from wikipedia doesn't work.
This PR fixes this.
