Gian Merlino 04e7c7fbdc FilteredRequestLogger: Fix start/stop, invalid delegate behavior. (#6637)
* FilteredRequestLogger: Fix start/stop, invalid delegate behavior.

Fixes two bugs:

1) FilteredRequestLogger did not start/stop the delegate.

2) FilteredRequestLogger would ignore an invalid delegate type, and
instead silently substitute the "noop" logger. This was due to a larger
problem with RequestLoggerProvider setup in general; the fix here is
to remove "defaultImpl" from the RequestLoggerProvider interface, and
instead have JsonConfigurator be responsible for creating the
default implementations. It is stricter about things than the old system
was, and is only willing to make a noop logger if it doesn't see any
request logger configs. Otherwise, it'll raise a provision error.

* Remove unneeded annotations.

Deiwin Sarjas e0d1dc5846 Support DogStatsD style tags in statsd-emitter (#6605)
* Replace StatsD client library

The [Datadog package][1] is a StatsD compatible drop-in replacement for the
client library, but it seems to be [better maintained][2] and has support for
Datadog DogStatsD specific features, which will be made use of in a subsequent
commit.

The `count`, `time`, and `gauge` methods are actually exactly compatible with
the previous library and the modifications shouldn't be required, but EasyMock
seems to have a hard time dealing with the variable arguments added by the
DogStatsD library and causes tests to fail if no arguments are provided for the
last String vararg. Passing an empty array fixes the test failures.

[1]: https://github.com/DataDog/java-dogstatsd-client
[2]: https://github.com/tim-group/java-statsd-client/issues/37#issuecomment-248698856

* Retain dimension key information for StatsD metrics

This doesn't change behavior, but allows separating dimensions from the metric
name in subsequent commits.

There is a possible order change for values from
`dimsBuilder.build().values()`, but from the tests it looks like it doesn't
affect actual behavior and the order of user dimensions is also retained.

* Support DogStatsD style tags in statsd-emitter

Datadog [doesn't support name-encoded dimensions and uses a concept of _tags_
instead.][1] This change allows Datadog users to send the metrics without
having to encode the various dimensions in the metric names. This enables
building graphs and monitors with and without aggregation across various
dimensions from the same data.

As tests in this commit verify, the behavior remains the same for users who
don't enable the `druid.emitter.statsd.dogstatsd` configuration flag.

[1]: https://www.datadoghq.com/blog/the-power-of-tagged-metrics/#tags-decouple-collection-and-reporting

* Disable convertRange behavior for DogStatsD users

DogStatsD, unlike regular StatsD, supports floating-point values, so this
behavior is unnecessary. It would be possible to still support `convertRange`,
even with `dogstatsd` enabled, but that would mean that people using the
default mapping would have some of the gauges unnecessarily converted.

`time` is in milliseconds and doesn't support floating-point values.

Clint Wylie 91a37c692d 'suspend' and 'resume' support for supervisors (kafka indexing service, materialized views) (#6234)
* 'suspend' and 'resume' support for kafka indexing service
changes:
* introduces `SuspendableSupervisorSpec` interface to describe supervisors which support suspend/resume functionality controlled through the `SupervisorManager`, which will gracefully shutdown the supervisor and it's tasks, update it's `SupervisorSpec` with either a suspended or running state, and update with the toggled spec. Spec updates are provided by `SuspendableSupervisorSpec.createSuspendedSpec` and `SuspendableSupervisorSpec.createRunningSpec` respectively.
* `KafkaSupervisorSpec` extends `SuspendableSupervisorSpec` and now supports suspend/resume functionality. The difference in behavior between 'running' and 'suspended' state is whether the supervisor will attempt to ensure that indexing tasks are or are not running respectively. Behavior is identical otherwise.
* `SupervisorResource` now provides `/druid/indexer/v1/supervisor/{id}/suspend` and `/druid/indexer/v1/supervisor/{id}/resume` which are used to suspend/resume suspendable supervisors
* Deprecated `/druid/indexer/v1/supervisor/{id}/shutdown` and moved it's functionality to `/druid/indexer/v1/supervisor/{id}/terminate` since 'shutdown' is ambiguous verbage for something that effectively stops a supervisor forever
* Added ability to get all supervisor specs from `/druid/indexer/v1/supervisor` by supplying the 'full' query parameter `/druid/indexer/v1/supervisor?full` which will return a list of json objects of the form `{"id":<id>, "spec":<SupervisorSpec>}`
* Updated overlord console ui to enable suspend/resume, and changed 'shutdown' to 'terminate'

* move overlord console status to own column in supervisor table so does not look like garbage

* spacing

* padding

* other kind of spacing

* fix rebase fail

* fix more better

* all supervisors now suspendable, updated materialized view supervisor to support suspend, more tests

* fix log

Cache: Add maxEntrySize config, make groupBy cacheable by default. (#5108)
* Cache: Add maxEntrySize config.

The idea is this makes it more feasible to cache query types that
can potentially generate large result sets, like groupBy and select,
without fear of writing too much to the cache per query.

Includes a refactor of cache population code in CachingQueryRunner and
CachingClusteredClient, such that they now use the same CachePopulator
interface with two implementations: one for foreground and one for
background.

The main reason for splitting the foreground / background impls is
that the foreground impl can have a more effective implementation of
maxEntrySize. It can stop retaining subvalues for the cache early.

* Add CachePopulatorStats.

* Fix whitespace.

* Fix docs.

* Fix various tests.

* Add tests.

Surekha 13c616ba24 'maxBytesInMemory' tuningConfig introduced for ingestion tasks (#5583)
* This commit introduces a new tuning config called 'maxBytesInMemory' for ingestion tasks

Currently a config called 'maxRowsInMemory' is present which affects how much memory gets
used for indexing.If this value is not optimal for your JVM heap size, it could lead
to OutOfMemoryError sometimes. A lower value will lead to frequent persists which might
be bad for query performance and a higher value will limit number of persists but require
more jvm heap space and could lead to OOM.
'maxBytesInMemory' is an attempt to solve this problem. It limits the total number of bytes
kept in memory before persisting.

 * The default value is 1/3(Runtime.maxMemory())
 * To maintain the current behaviour set 'maxBytesInMemory' to -1
 * If both 'maxRowsInMemory' and 'maxBytesInMemory' are present, both of them
   will be respected i.e. the first one to go above threshold will trigger persist

Jakub Kukul e2431ae161 Update defaultHadoopCoordinates in documentation. (#5720)
* Update defaultHadoopCoordinates in documentation.

To match changes applied in #5382.

* Remove a parameter with defaults from example configuration file.

If it has reasonable defaults, then why would it be in an example config file?

Also, it is yet another place that has been forgotten to be updated and will be forgotten in the future.

Also, if someone is running different hadoop version, then there's much more work to be done than just changing this property, so why give users false hopes?

* Fix typo in documentation.
