* If a worker dies after it has finished generating results, MSQ decides to not retry it as it has no active work orders. However, since we don't keep track of it further, if it is required for a future stage, the controller hangs waiting for the worker to be ready. This PR keeps tracks of any workers the controller decides to not restart immediately and while starting workers for the next stage, queues these workers for retry.

Hadoop 2 often causes red security scans on Druid distribution because of the dependencies it brings. We want to move away from Hadoop 2 and provide Hadoop 3 distribution available. Switch druid to building with Hadoop 3 by default. Druid will still be compatible with Hadoop 2 and users can build hadoop-2 compatible distribution using hadoop2 profile.
* Fix two concurrency issues with segment fetching.
1) SegmentLocalCacheManager: Fix a concurrency issue where certain directory
cleanup happened outside of directoryWriteRemoveLock. This created the
possibility that segments would be deleted by one thread, while being
actively downloaded by another thread.
2) TaskDataSegmentProcessor (MSQ): Fix a concurrency issue when two stages
in the same process both use the same segment. For example: a self-join
using distributed sort-merge. Prior to this change, the two stages could
delete each others' segments.
3) ReferenceCountingResourceHolder: increment() returns a new ResourceHolder,
rather than a Releaser. This allows it to be passed to callers without them
having to hold on to both the original ResourceHolder *and* a Releaser.
4) Simplify various interfaces and implementations by using ResourceHolder
instead of Pair and instead of split-up fields.
* Add test.
* Fix style.
* Remove Releaser.
* Updates from master.
* Add some GuardedBys.
* Use the correct GuardedBy.
* Adjustments.
* Improved handling for zero-length intervals.
1) Return an empty list from VersionedIntervalTimeline.lookup when
provided with an empty interval. (The logic doesn't quite work when
intervals are empty, which led to #14129.)
2) Don't return zero-length intervals from JodaUtils.condenseIntervals.
3) Detect "incorrect" comparator in JodaUtils.condenseIntervals, and
recreate the SortedSet if needed. (Not strictly related to the theme
of this patch. Just another thing in the same file.)
4) Remove unused method JodaUtils.containOverlappingIntervals.
Fixes#14129.
* Fix TimewarpOperatorTest.
* Compaction: Block input specs not aligned with segmentGranularity.
When input intervals are not aligned with segmentGranularity, data may be
overshadowed if it lies in the space between the input intervals and the
output segmentGranularity.
In MSQ REPLACE, this is a validation error. IMO the same behavior makes
sense for compaction tasks. In case anyone was depending on the ability
to compact nonaligned intervals, a configuration parameter
allowNonAlignedInterval is provided. I don't expect it to be used much.
* Remove unused.
* ITCompactionTaskTest uses non-aligned intervals.
* MSQ: Subclass CalciteJoinQueryTest, other supporting changes.
The main change is the new tests: we now subclass CalciteJoinQueryTest
in CalciteSelectJoinQueryMSQTest twice, once for Broadcast and once for
SortMerge.
Two supporting production changes for default-value mode:
1) InputNumberDataSource is marked as concrete, to allow leftFilter to
be pushed down to it.
2) In default-value mode, numeric frame field readers can now return nulls.
This is necessary when stacking joins on top of joins: nulls must be
preserved for semantics that match broadcast joins and native queries.
3) In default-value mode, StringFieldReader.isNull returns true on empty
strings in addition to nulls. This is more consistent with the behavior
of the selectors, which map empty strings to null as well in that mode.
As an effect of change (2), the InsertTimeNull change from #14020 (to
replace null timestamps with default timestamps) is reverted. IMO, this
is fine, as either behavior is defensible, and the change from #14020
hasn't been released yet.
* Adjust tests.
* Style fix.
* Additional tests.
When ingesting from an external source which already contains a column "__time", currently, the value is dropped. Changing the time column name in the external input slice reader resolves this.
* return task status reported by peon
* Write TaskStatus to file in AbstractTask.cleanUp
* Get TaskStatus from task log
* Fix merge conflicts in AbstractTaskTest
* Add unit tests for TaskLogPusher, TaskLogStreamer, NoopTaskLogs to satisfy code coverage
* Add license headerss
* Fix style
* Remove unknown exception declarations
* Allow for Log4J to be configured for peons but still ensure console logging is enforced
This change will allow for log4j to be configured for peons but require console logging is still
configured for them to ensure peon logs are saved to deep storage.
Also fixed the test ConsoleLoggingEnforcementTest to use a valid appender for the non console
Config as the previous config was incorrect and would never return a logger.
* fix checkstyle
* add warning to logger when it overwrites all loggers to be console
* optimize calls for altering logging config for ConsoleLoggingEnforcementConfigurationFactory
add getName to the druid logger class
* update docs, and error message
* edit docs to be more clear
* fix checkstyle issues
* CI fixes - LoggerTest code coverage and fix spelling issue for logging docs
* SQL planning: Consider subqueries in fewer scenarios.
Further adjusts logic in DruidRules that was previously adjusted in #13902.
The reason for the original change was that the comment "Subquery must be
a groupBy, so stage must be >= AGGREGATE" was no longer accurate. Subqueries
do not need to be groupBy anymore; they can really be any type of query.
If I recall correctly, the change was needed for certain window queries
to be able to plan on top of Scan queries.
However, this impacts performance negatively, because it causes many
additional outer-query scenarios to be considered, which is expensive.
So, this patch updates the matching logic to consider fewer scenarios. The
skipped scenarios are ones where we expect that, for one reason or another,
it isn't necessary to consider a subquery.
* Remove unnecessary escaping.
* Fix test.
* Updating segment map function for QueryDataSource to ensure group by of group by of join data source gets into proper segment map function path
* Adding unit tests for the failed case
* There you go coverage bot, be happy now
* Refresh DruidLeaderClient cache for non-200 responses
* Change local variable name to avoid confusion
* Implicit retries for 503 and 504
* Remove unused imports
* Use argumentmatcher instead of Mockito for #any in test
* Remove flag to disable retry for 503/504
* Remove unused import from test
* Add log line for internal retry

### Description
This pr fixes a few bugs found with the inputSource security feature.
1. `KillUnusedSegmentsTask` previously had no definition for the `getInputSourceResources`, which caused an unsupportedOperationException to be thrown when this task type was submitted with the inputSource security feature enabled. This task type should not require any input source specific resources, so returning an empty set for this task type now.
2. Fixed a bug where when the input source type security feature is enabled, all of the input source type specific resources used where authenticated against:
`{"resource": {"name": "EXTERNAL", "type": "{INPUT_SOURCE_TYPE}"}, "action": "READ"}`
When they should be instead authenticated against:
`{"resource": {"name": "{INPUT_SOURCE_TYPE}", "type": "EXTERNAL"}, "action": "READ"}`
3. fixed bug where supervisor tasks were not authenticated against the specific input source types used, if input source security feature was enabled.
*
Adds new run time parameter druid.indexer.task.tmpStorageBytesPerTask. This sets a limit for the amount of temporary storage disk space used by tasks. This limit is currently only respected by MSQ tasks.
* Removes query context parameters intermediateSuperSorterStorageMaxLocalBytes and composedIntermediateSuperSorterStorageEnabled. Composed intermediate super sorter (which was enabled by composedIntermediateSuperSorterStorageEnabled) is now enabled automatically if durableShuffleStorage is set to true. intermediateSuperSorterStorageMaxLocalBytes is calculated from the limit set by the run time parameter druid.indexer.task.tmpStorageBytesPerTask.
* "maxResultsSize" has been removed from the S3OutputConfig and a default "chunkSize" of 100MiB is now present. This change primarily affects users who wish to use durable storage for MSQ jobs.
This commit adds attributes that contain metadata information about the query
in the EXPLAIN PLAN output. The attributes currently contain two items:
- `statementTyp`: SELECT, INSERT or REPLACE
- `targetDataSource`: provides the target datasource name for DML statements
It is added to both the legacy and native query plan outputs.
* SQL: Fix natural comparator selection for groupBy.
DruidQuery.computeSorting had some unique logic for finding natural
comparators for SQL types. It should be using getStringComparatorForRelDataType
instead.
One good effect here is that the comparator for BOOLEAN is now
NUMERIC rather than LEXICOGRAPHIC. The test case illustrates this.
* Remove msqCompatible, for now.
* Fix test.
* MSQ: Use the same result coercion routines as the regular SQL endpoint.
The main changes are to move NativeQueryMaker.coerce to SqlResults, and
to formally make the list of sqlTypeNames from the MSQ results reports
use SqlTypeNames.
- Change the default to MSQ-compatible rather than MSQ-incompatible.
The explicit marker function is now "notMsqCompatible()".
* MSQ: Support for querying lookup and inline data directly.
Main changes:
1) Add of LookupInputSpec and DataSourcePlan.forLookup.
2) Add InlineInputSpec, and modify of DataSourcePlan.forInline to use
this instead of an ExternalInputSpec with JSON. This allows the inline
data to act as the right-hand side of a join, if needed.
Supporting changes:
1) Modify JoinDataSource's leftFilter validation to be a little less
strict: it's now OK with leftFilter being attached to any concrete
leaf (no children) datasource, rather than requiring it be a table.
This allows MSQ to create JoinDataSource with InputNumberDataSource
as the base.
2) Add SegmentWranglerModule to CliIndexer, CliPeon. This allows them to
query lookups and inline data directly.
* Updates based on CI.
* Additional tests.
* Style fix.
* Remove unused import.
