Native batch indexing doesn't yet support the maxParseExceptions,
maxSavedParseExceptions, and logParseExceptions tuning config options, so
ParallelIndexSupervisorTask logs if these are set. But the default value for
maxParseExceptions is Integer.MAX_VALUE, which means that you'll get the
maxParseExceptions flavor of this warning even if you don't configure
maxParseExceptions.
This PR changes all three warnings to occur if you change the settings from the
default; this mostly affects the maxParseExceptions warning.
* Prohibit assigning concurrent maps into Map-types variables and fields; Fix a race condition in CoordinatorRuleManager; improve logic in DirectDruidClient and ResourcePool
* Enforce that if compute(), computeIfAbsent(), computeIfPresent() or merge() is called on a ConcurrentHashMap, it's stored in a ConcurrentHashMap-typed variable, not ConcurrentMap; add comments explaining get()-before-computeIfAbsent() optimization; refactor Counters; fix a race condition in Intialization.java
* Remove unnecessary comment
* Checkstyle
* Fix getFromExtensions()
* Add a reference to the comment about guarded computeIfAbsent() optimization; IdentityHashMap optimization
* Fix UriCacheGeneratorTest
* Workaround issue with MaterializedViewQueryQueryToolChest
* Strengthen Appenderator's contract regarding concurrency
* Add published segment cache in broker
* Change the DataSegment interner so it's not based on DataSEgment's equals only and size is preserved if set
* Added a trueEquals to DataSegment class
* Use separate interner for realtime and historical segments
* Remove trueEquals as it's not used anymore, change log message
* PR comments
* PR comments
* Fix tests
* PR comments
* Few more modification to
* change the coordinator api
* removeall segments at once from MetadataSegmentView in order to serve a more consistent view of published segments
* Change the poll behaviour to avoid multiple poll execution at same time
* minor changes
* PR comments
* PR comments
* Make the segment cache in broker off by default
* Added a config to PlannerConfig
* Moved MetadataSegmentView to sql module

* PR comments
* fix test
* remove unintentional change, whether to synchronize on lifecycleLock is still in discussion in PR
* minor changes
* some changes to initialization
* use pollPeriodInMS
* Add boolean cachePopulated to check if first poll succeeds
* Remove poll from start()
* take the log message out of condition in stop()
* Some adjustments to config examples.
- Add ExitOnOutOfMemoryError to jvm.config examples. It was added a
pretty long time ago (8u92) and is helpful since it prevents zombie
processes from hanging around. (OOMEs tend to bork things)
- Disable Broker caching and enable it on Historicals in example
configs. This config tends to scale better since it enables the
Historicals to merge results rather than sending everything by-segment
to the Broker. Also switch to "caffeine" cache from "local".
- Increase concurrency a bit for Broker example config.
- Enable SQL in the example config, a baby step towards making SQL
more of a thing. (It's still off by default in the code.)
- Reduce memory use a bit for the quickstart configs.
- Add example Router configs, in case someone wants to use that. One
reason might be to get the fancy new console (#6923).
* Add example Router configs.
* Fix up router example properties.
* Add router to quickstart supervise conf.
