* 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
* Fix round robining in router.
Say that ten times fast.
For query endpoints, AsyncQueryForwardingServlet called hostFinder.getDefaultServer()
to set a default server, followed by hostFinder.getServer(inputQuery) to override it
with query-specific routing. Since hostFinder is round-robin, this skips a server.
When there are only two servers, one server is _always_ skipped and the router sends
all queries to the same broker.
* Adjust spacing.
* adding a properties endpoint in status resource
* checkstyle fixes
* more checkstyle corrections
* correcting the resource filter for properties endpoint
* adding feature of hiding sensitive properties
* checkstyle changes
* review changes for adding default hidden properties and using jackson for arrays value
* making review changes
* 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
* Properly set "identity" in query metrics.
This patch adds an "identity" field to QueryPlus and sets it in
QueryLifecycle when the query starts executing. This is important
because it allows it to be used for future QueryMetrics created
by that QueryPlus object.
We also add "identity" to the request-level QueryMetrics object
created in emitLogsAndMetrics.
* Remove unused method.
* 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
* Fix races in LookupSnapshotTaker, CoordinatorPollingBasicAuthenticatorCacheManager.
Both were susceptible to the following conditions:
1. Two JVMs on the same machine (perhaps two peons) could conflict by one reading while the
other was writing, or by writing to the file at the same time.
2. One JVM could partially write a file, then crash, leaving a truncated file.
* Use StringUtils.format
* Use both Joad Ids and Java IDs as Timezone to string readers
Change-Id: Ieb5c18559879f3f3a0104912ce2f0a354ad0aac3
* move the function to DateTimes and add org.joda.time.DateTimeZone#forID as part of forbidden api
Change-Id: Iff97fa044758019ed0c231587d10e31a9cc18da0
* exclude class and remove other usage
Change-Id: Ib458c2caaa1865535767e1009fbf017a92c8f615
* remove it from test classes
Change-Id: I9b576324f6c7e17a74bd8b13879232c9a8cd40b4
* remove unused

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.
Also remove Guice annotations from LoadQueueTaskMaster, since it is
provided by CliCoordinator, so Guice does not need to know how to
build one directly.
Code changes:
- In the lookup-based extractionFns, inherit injective property from
the lookup itself if not specified.
Doc changes:
- Add a "Query execution" section to the lookups doc explaining how
injective lookups and their optimizations work.
- Remove scary warnings against using registeredLookup extractionFns.
They are necessary and important since they work with filters and
function cascades -- two things that the dimension specs do not do.
They deserve to be first class citizens.
- Move the "registeredLookup" fn above the "lookup" fn. It's probably
more commonly used, so the docs read better this way.
* 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
* Fix broken KafkaEmitterConfig parsing
This was a regression introduced in
https://github.com/druid-io/druid/pull/4722
KafkaEmitterConfig property names have dot(.) in the name of properties
and JsonConfigurator behavior was changed to not support that.
Added a test and fixed parsing of properties that have dot(.) in
property names
* Fix test failure
* Add freeSpacePercent config in segment location config to enforce free space while storing segments
* address review comments
* address review comments: more doc on freeSpacePercent and use Double for freeSpacePercent
