Nishant Bangarwa fdc03bd336 [druid-kerberos] Fix checking of host URI when reading cookies from cookie store (#7825)
Reading of auth cookie was not checking URI of the server where request was being sent.  This was causing cookie set for one server to be sent to another one and extra authentication round trips between internal druid services.

SQL: Allow select-sort-project query shapes. (#7769)
* SQL: Allow select-sort-project query shapes.

Fixes #7768.

Design changes:

- In PartialDruidQuery, allow projection after select + sort by removing
  the SELECT_SORT query stage and instead allowing the SORT and
  SORT_PROJECT stages to apply either after aggregation or after a plain
  non-aggregating select. This is different from prior behavior, where
  SORT and SORT_PROJECT were only considered valid after aggregation
  stages. This logic change is in the "canAccept" method.
- In DruidQuery, represent either kind of sorting with a single "Sorting"
  class (instead of DefaultLimitSpec). The Sorting class is still
  convertible into a DefaultLimitSpec, but is also convertible into the
  sorting parameters accepted by a Scan query.
- In DruidQuery, represent post-select and post-sorting projections with
  a single "Projection" class. This obsoletes the SortProject and
  SelectProjection classes, and simplifies the DruidQuery by allowing us
  to move virtual-column and post-aggregator-creation logic into the
  new Projection class.
- Split "DruidQuerySignature" into RowSignature and VirtualColumnRegistry.
  This effectively means that instead of having mutable and immutable
  versions of DruidQuerySignature, we instead of RowSignature (always
  immutable) and VirtualColumnRegistry (always mutable, but sometimes
  null). This change wasn't required, but IMO it this makes the logic
  involving them easier to follow, and makes it more clear when the
  virtual column registry is active and when it's not.

Other changes:

- ConvertBoundsToSelectors now just accepts a RowSignature, but we
  use the VirtualColumnRegistry.getFullRowSignature() method to get
  a signature that includes all columns, and therefore allows us to
  simplify the logic (no need to special-case virtual columns).
- Add `__time` to the Scan column list if the query is ordering by time.

* Remove unused import.

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
