* Future-proof some Guava usage
* Use a java-util EmptyIterator instead of Guava's
* Change some of the guava future handling to do manual async
transforms. Guava changes transform into transformAsync by deprecating
transform in ONLY Guava 19. Then its gone in 20
* Use `Collections.emptyIterator()`
* Pretty formatting
* Make listenable future transforms a thing in default druid
* Format fix
* Add forbidden guava apis
* Make the ListenableFutrues.transformAsync have comments
* Undo intellij bad pattern matching in comments
* Futrues --> Futures
* Add empty iterators forbidding
* Fix extra `A`
* Correct method signature
* Address review comments
* Finish Gian review comments
* Proper syntax from https://github.com/policeman-tools/forbidden-apis/wiki/SignaturesSyntax
and added datasource information as part of existing endpoint /druid/indexer/v1/runningTasks.
Added junit test cases for the newly implemented API and fixed existing junit test cases.
Fixed review comments - added new method getCreatedDateTimeAndDataSource into TaskStorageQueryAdapter class
and formatted changed files
* Support for disabling bitmap indexes.
Can save space for columns where bitmap indexes are pointless (like
free-form text).
* Remove import.
* Fix CompactionTaskTest.
* Update for review comments.
* Review comments, tests.
* Fix test.
* Fix missing task type in task payload API.
Apparently embedding a polymorphic object inside a Map<String, Object> is
a bit too much for Jackson to serialize properly. Fix this by using
wrapper classes.
* Fix OverlordTest casts.
* Remove import.
* Remove unused imports.
* Clarify comments.
* Fix early publishing to early pushing in batch indexing & refactor appenderatorDriver
* fix compile
* rename and add more javadocs
* Fix conflicts
* address comments
* revert await executors
* fix test
* Change RealtimeIndexTask to use AppenderatorDriver instead of RealtimePlumber. Related to #4774
* Remove unused throwableDuringPublishing
* Fix usage of forbidden API
* Update realtime index IT to account for not skipping older data any more
* Separate out waiting on publish futures and handoff futures to avoid a race condition where the handoff timeout expires before the segment is published
* #5261 Add separate AppenderatorDriverRealtimeIndexTask and revert changes to RealtimeIndexTask
* #5261 Add separate AppenderatorDriverRealtimeIndexTask and revert changes to RealtimeIndexTask
* #5261 Readability improvements in AppenderatorDriverRealtimeIndexTask. Combine publish and handoff futures in to single future
* #5261 Add separate tuningConfig for RealtimeAppenderatorIndexTask. Revert changes to RealtimeTuningConfig
* #5261 Change JSON type to realtime_appenderator to keep the same naming pattern as RealtimeIndexTask
The behavior is configurable through druid.extensions.useExtensionClassloaderFirst.
It is useful when extensions want to load a dependency different from one provided
by Druid, for example a different version of geoip or protobuf.
* just renaming of SegmentChangeRequestHistory etc
* additional change history refactoring changes
* WorkerTaskManager a replica of WorkerTaskMonitor
* HttpServerInventoryView refactoring to extract sync code and robustification
* Introducing HttpRemoteTaskRunner
* Additional Worker side updates
* Deduplicate DataSegments contents (loadSpec's keys, dimensions and metrics lists as a whole) more aggressively; use ArrayMap instead of default LinkedHashMap for DataSegment.loadSpec, because they have only 3 entries on average; prune DataSegment.loadSpec on brokers
* Fix DataSegmentTest
* Refinements
* Try to fix
* Fix the second DataSegmentTest
* Nullability
* Fix tests
* Fix tests, unify to use TestHelper.getJsonMapper()
* Revert TestUtil as ServerTestHelper, fix tests
* Add newline
* Fix indexing tests
* Fix s3 tests
* Try to fix tests, remove lazy caching of ObjectMapper in TestHelper, rename TestHelper.getJsonMapper() to makeJsonMapper()
* Fix HDFS tests
* Fix HdfsDataSegmentPusherTest
* Capitalize constant names
* Kafka Index Task that supports Incremental handoffs
- Incrementally handoff segments when they hit maxRowsPerSegment limit
- Decouple segment partitioning from Kafka partitioning, all records from consumed partitions go to a single druid segment
- Support for restoring task on middle manager restarts by check pointing end offsets for segments
* take care of review comments
