Gian Merlino a8c7132482 Logic adjustments to SeekableStreamIndexTaskRunner. (#7267)
* Logic adjustments to SeekableStreamIndexTaskRunner.

A mix of simplifications and bug fixes. They are intermingled because
some of the bugs were made difficult to fix, and also more likely to
happen in the first place, by how the code was structured. I tried to
keep restructuring to a minimum. The changes are:

- Remove "initialOffsetsSnapshot", which was used to determine when to
  skip start offsets. Replace it with "lastReadOffsets", which I hope
  is more intuitive. (There is a connection: start offsets must be
  skipped if and only if they have already been read, either by a
  previous task or by a previous sequence in the same task, post-restoring.)
- Remove "isStartingSequenceOffsetsExclusive", because it should always
  be the opposite of isEndOffsetExclusive. The reason is that starts are
  exclusive exactly when the prior ends are inclusive: they must match
  up in that way for adjacent reads to link up properly.
- Don't call "seekToStartingSequence" after the initial seek. There is
  no reason to, since we expect to read continuous message streams
  throughout the task. And calling it makes offset-tracking logic
  trickier, so better to avoid the need for trickiness. I believe the
  call being here was causing a bug in Kinesis ingestion where a
  message might get double-read.
- Remove the "continue" calls in the main read loop. They are bad
  because they prevent keeping currOffsets and lastReadOffsets up to
  date, and prevent us from detecting that we have finished reading.
- Rework "verifyInitialRecordAndSkipExclusivePartition" into
  "verifyRecordInRange". It no longer has side effects. It does a sanity
  check on the message offset and also makes sure that it is not past
  the endOffsets.
- Rework "assignPartitions" to replace inline comparisons with
  "isRecordAlreadyRead" and "isMoreToReadBeforeReadingRecord" calls. I
  believe this fixes an off-by-one error with Kinesis where the last
  record would not get read. It also makes the logic easier to read.
- When doing the final publish, only adjust end offsets of the final
  sequence, rather than potentially adjusting any unpublished sequence.
  Adjusting sequences other than the last one is a mistake since it
  will extend their endOffsets beyond what they actually read. (I'm not
  sure if this was an issue in practice, since I'm not sure if real
  world situations would have more than one unpublished sequence.)
- Rename "isEndSequenceOffsetsExclusive" to "isEndOffsetExclusive". It's
  shorter and more clear, I think.
- Add equals/hashCode/toString methods to OrderedSequenceNumber.

Kafka test changes:

- Added a Kafka "testRestoreAtEndOffset" test to verify that restores at
  the very end of the task lifecycle still work properly.

Kinesis test changes:

- Renamed "testRunOnNothing" to "testRunOnSingletonRange". I think that
  given Kinesis semantics, the right behavior when start offset equals
  end offset (and there aren't exclusive partitions set) is to read that
  single offset. This is because they are both meant to be treated as
  inclusive.
- Adjusted "testRestoreAfterPersistingSequences" to expect one more
  message read. I believe the old test was wrong; it expected the task
  not to read message number 5.
- Adjusted "testRunContextSequenceAheadOfStartingOffsets" to use a
  checkpoint starting from 1 rather than 2. I believe the old test was
  wrong here too; it was expecting the task to start reading from the
  checkpointed offset, but it actually should have started reading from
  one past the checkpointed offset.
- Adjusted "testIncrementalHandOffReadsThroughEndOffsets" to expect
  11 messages read instead of 12. It's starting at message 0 and reading
  up to 10, which should be 11 messages.

David Glasser 1c2753ab90 ParallelIndexSubTask: support ingestSegment in delegating factories (#7089)
IndexTask had special-cased code to properly send a TaskToolbox to a
IngestSegmentFirehoseFactory that's nested inside a CombiningFirehoseFactory,
but ParallelIndexSubTask didn't.

This change refactors IngestSegmentFirehoseFactory so that it doesn't need a
TaskToolbox; it instead gets a CoordinatorClient and a SegmentLoaderFactory
directly injected into it.

This also refactors SegmentLoaderFactory so it doesn't depend on
an injectable SegmentLoaderConfig, since its only method always
replaces the preconfigured SegmentLoaderConfig anyway.
This makes it possible to use SegmentLoaderFactory without setting
druid.segmentCaches.locations to some dummy value.

Another goal of this PR is to make it possible for IngestSegmentFirehoseFactory
to list data segments outside of connect() --- specifically, to make it a
FiniteFirehoseFactory which can query the coordinator in order to calculate its
splits. See #7048.

This also adds missing datasource name URL-encoding to an API used by
CoordinatorBasedSegmentHandoffNotifier.

Ankit Kothari 8492d94f59 Kill Hadoop MR task on kill of Hadoop ingestion task (#6828)
* KillTask from overlord UI now makes sure that it terminates the underlying MR job, thus saving unnecessary compute

Run in jobby is now split into 2
 1. submitAndGetHadoopJobId followed by 2. run
  submitAndGetHadoopJobId is responsible for submitting the job and returning the jobId as a string, run monitors this job for completion

JobHelper writes this jobId in the path provided by HadoopIndexTask which in turn is provided by the ForkingTaskRunner

HadoopIndexTask reads this path when kill task is clicked to get hte jobId and fire the kill command via the yarn api. This is taken care in the stopGracefully method which is called in SingleTaskBackgroundRunner. Have enabled `canRestore` method to return `true` for HadoopIndexTask in order for the stopGracefully method to be called

Hadoop*Job files have been changed to incorporate the changes to jobby

* Addressing PR comments

* Addressing PR comments - Fix taskDir

* Addressing PR comments - For changing the contract of Task.stopGracefully()

* Addressing PR comments

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

Gian Merlino 5ce3185b9c Fix three bugs with segment publishing. (#6155)
* Fix three bugs with segment publishing.

1. In AppenderatorImpl: always use a unique path if requested, even if the segment
   was already pushed. This is important because if we don't do this, it causes
   the issue mentioned in #6124.
2. In IndexerSQLMetadataStorageCoordinator: Fix a bug that could cause it to return
   a "not published" result instead of throwing an exception, when there was one
   metadata update failure, followed by some random exception. This is done by
   resetting the AtomicBoolean that tracks what case we're in, each time the
   callback runs.
3. In BaseAppenderatorDriver: Only kill segments if we get an affirmative false
   publish result. Skip killing if we just got some exception. The reason for this
   is that we want to avoid killing segments if they are in an unknown state.

Two other changes to clarify the contracts a bit and hopefully prevent future bugs:

1. Return SegmentPublishResult from TransactionalSegmentPublisher, to make it
more similar to announceHistoricalSegments.
2. Make it explicit, at multiple levels of javadocs, that a "false" publish result
must indicate that the publish _definitely_ did not happen. Unknown states must be
exceptions. This helps BaseAppenderatorDriver do the right thing.

* Remove javadoc-only import.

* Updates.

* Fix test.

* Fix tests.

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.

* Fix 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

Kafka: Fixes needlessly low interpretation of maxRowsInMemory. (#5034)
AppenderatorImpl already applies maxRowsInMemory across all sinks. So dividing by
the number of Kafka partitions is pointless and effectively makes the interpretation
of maxRowsInMemory lower than expected.

This undoes one of the two changes from #3284, which fixed the original bug twice.
In this, that's worse than fixing it once.

Gian Merlino 6c725a7e06 Fix havingSpec on complex aggregators. (#5024)
* 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.

Gian Merlino 0ce406bdf1
Introduce "transformSpec" at ingest-time. (#4890)
* 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.

* Add flattenSpec support to the Avro parser.

Also:

- Refactor the JSONPathParser a bit so it can share flattening code
  with Avro (see ObjectFlatteners).
- Remove the JSONParser. It was only used in two places: by
  UriNamespaceExtractor, and as a base for JSONToLowerParser. Migrated
  the former to JSONPathParser and made the latter a standalone.
- Move GenericRecordAsMap to the Parquet extension, since the Avro
  extension no longer uses it.

* Fix indentation.

of Kafka partitions...

Gian Merlino f22fb2c2cf KafkaIndexTask.

transactions to guarantee exactly-once ingestion.

Each task has a finite lifecycle, so it is expected that some process will be supervising
existing tasks and creating new ones when needed.
