* Fix havingSpec on complex aggregators.
- Uses the technique from #4883 on DimFilterHavingSpec too.
- Also uses Transformers from #4890, necessitating a move of that and other
related classes from druid-server to druid-processing. They probably make
more sense there anyway.
- Adds a SQL query test.
Fixes#4957.
* Remove unused import.
* Introduce "transformSpec" at ingest-time.
It accepts a "filter" (standard query filter object) and "transforms" (a
list of objects with "name" and "expression"). These can be used to do
filtering and single-row transforms without need for a separate data
processing job.
The "expression" fields use the same expression language as other
expression-based feature.
* Remove forbidden api.
* Fix compile error.
* Fix tests.
* Some more changes.
- Add nullable annotation to Firehose.nextRow.
- Add tests for index task, realtime task, kafka task, hadoop mapper,
and ingestSegment firehose.
* Fix bad merge.
* Adjust imports.
* Adjust whitespace.
* Make Transform into an interface.
* Add missing annotation.
* Switch logger.
* Switch logger.
* Adjust test.
* Adjustment to handling for DatasourceIngestionSpec.
* Fix test.

* Remove unused method.
* Add javadocs.
* More javadocs, and always decorate.
* Fix bug in TransformingStringInputRowParser.
* Fix bad merge.

* Changes for lookup synchronization
* Refactor of Lookup classes
* Minor refactors and doc update
* Change coordinator instance to be retrieved by DruidLeaderClient
* Wait before thread shutdown
* Make disablelookups flag true by default
* Update docs
* Rename flag
* Move executorservice shutdown to finally block
* Update LookupConfig
* Refactoring and doc changes
* Remove lookup config constructor
* Revert Lookupconfig constructor changes
* Add tests to LookupConfig
* Make executorservice local
* Update LRM
* Move ListeningScheduledExecutorService to ExecutorCompletionService
* Move exception to outer block
* Remove check to see future is done
* Remove unnecessary assignment
* Add logging
"No worker selection strategy set." would get logged any time tryAssignTask runs
in the default configuration, which is often. It also doesn't provide much value.
* Make AutoScaler, ProvisioningStrategy and BaseWorkerBehaviorConfig extension points; More logging in PendingTaskBasedWorkerProvisioningStrategy
* Address comments and fix a bug
* Extract method
* debug logging
* Rename BaseWorkerBehaviorConfig to WorkerBehaviorConfig and WorkerBehaviorConfig to DefaultWorkerBehaviorConfig
* Fixes
* remove ServerConfig from DruidNode as all information needs to be present in DruidNode serialized form
* sanitize output of /druid/coordinator/v1/cluster endpoint
* Use internal-discovery and http for talking to overlord/coordinator leaders
* CuratorDruidNodeDiscovery.getAllNodes() best effort 30 sec wait for cache initialization
* DruidLeaderClientProvider to eagerly instantiate DruidNodeDiscovery when needed so that DruidNodeDiscovery impl cache gets initialized well in time
* Revert "DruidLeaderClientProvider to eagerly instantiate DruidNodeDiscovery when needed so that DruidNodeDiscovery impl cache gets initialized well in time"
This reverts commit f1a2432614ba56ddc2d55fe47e990d17fcfd6129.
* add lifecycle to DruidLeaderClient to early initialize DruidNodeDiscovery so that it has its cache update well in time
* Collapse worker select strategies, change default, add strong affinity.
- Change default worker select strategy to equalDistribution. It is
more generally useful than fillCapacity.
- Collapse the *WithAffinity strategies into the regular ones. The
*WithAffinity strategies are retained for backwards compatibility.
- Change WorkerSelectStrategy to return nullable instead of Optional.
- Fix a couple of errors in the docs.
* Fix test.
* Review adjustments.
* Remove unused imports.
* Switch to DateTimes.nowUtc.
* Simplify code.
* Fix tests (worker assignment started off on a different foot)
* DruidLeaderSelector interface for leader election and Curator based impl. DruidCoordinator/TaskMaster are updated to use the new interface.
* add fake DruidNode binding in integration-tests module
* add docs on DruidLeaderSelector interface
* remove start/stop and keep register/unregister Listener in DruidLeaderSelector interface
* updated comments on DruidLeaderSelector
* cache the listener executor in CuratorDruidLeaderSelector
* use same latch owner name that was used before
* remove stuff related to druid.zk.paths.indexer.leaderLatchPath config
* randomize the delay when giving up leadership and restarting leader latch
