* fix serde error
* fix build
* 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.

* 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
* Add "round" option to cardinality and hyperUnique aggregators.
Also turn it on by default in SQL, to make math on distinct counts
work more as expected.
* Fix some compile errors.
* Fix test.
* Formatting.
* internal-discovery: interfaces for announcement/discovery, curator impls
* more tests
* address some review comments
* more fixes
* address more review comments
* simplify ObjectMapper setup in CuratorDruidNodeAnnouncerAndDiscoveryTest
* fix KafkaIndexTaskTest
* make lookupTier overridable via RealtimeIndexTask and KafkaIndexTask context
* make teamcity build happy
* Stop RemoteTaskRunner's cleanupExec using TaskMaster's lifecycle, not global injected lifecycle
* Prohibit starting Lifecycle twice; Make Lifecycle to reject addMaybeStartHandler() attempts in the process of stopping rather than entering deadlock
* Fix Lifecycle.addMaybeStartHandler()
* Remove RemoteTaskRunnerFactoryTest
* Add docs
* Language
* Address comments
* Fix RemoteTaskRunnerTestUtils
This allows the tasks to run concurrently. Additionally, rework
the partition-determining code in a couple ways:
- Use a task-id based sequenceName so concurrently running append
tasks do not clobber each others' segments.
- Make the list of shardSpecs empty when rollup is non-guaranteed, and
let allocators handle the creation of incremental shardSpecs.
* Rename ResourceManagementStrategy to ProvisioningStrategy, similarly for related classes. Make ProvisioningService non-global, created per RemoteTaskRunner instead. Add OverlordBlinkLeadershipTest.
* Fix RemoteTaskRunnerFactoryTest.testExecNotSharedBetweenRunners()
* Small fix
* Make SimpleProvisioner and PendingProvisioner more similar in details
* Fix executor name
* Style fixes
* Use LifecycleLock in RemoteTaskRunner
* Remove some unnecessary use of boxed types.
* Fix some incorrect format strings.
* Enable IDEA's MalformedFormatString inspection.
* Add a Checkstyle check for finding uses of incorrect logging packages.
* Fix some incorrect usages of the metamx logger.
* Bypass incorrect logger Checkstyle check where using the correct logger is not simple.
* Fix some more places where the wrong number of arguments are provided to format strings.
* Suppress `MalformedFormatString` inspection on legacy logging test.
* Use @SuppressWarnings rather than a noinspection suppression comment.
* Fix some more incorrect format strings.
* Suppress some more incorrect format string warnings where the incorrect string is intentional.
* Log the aggregator when closing it fails.
* Remove some unneeded log lines.
* Early publishing segments in the middle of data ingestion
* Remove unnecessary logs
