This change allows the selection of a specific broker service (or broker tier) by the Router.
The newly added ManualTieredBrokerSelectorStrategy works as follows:
Check for the parameter brokerService in the query context. If this is a valid broker service, use it.
Check if the field defaultManualBrokerService has been set in the strategy. If this is a valid broker service, use it.
Move on to the next strategy
This PR fixes an issue with the integration test copy_resources.sh script.
The "install druid jars" portion was removing the $SHARED_DIR/docker directory, which wipes out the $SHARED_DIR/docker/extensions and $SHARED_DIR/docker/credentials directories created just before, which leads to issues later in the script when copying resources to the $SHARED_DIR/docker/credentials/ dir.
* HLL lgK and a tip
Knowledge transfer from https://the-asf.slack.com/archives/CJ8D1JTB8/p1600699967024200. Attempted to make a connection between the SQL HLL function and the HLL underneath without getting too complicated. Also added a note about using K over 16 being pretty much pointless.
* Corrected spelling
* Create datasketches-hll.md
Put roll-up back to rollup

This PR fixes the incorrect results for query :
SELECT dim1, l1.k FROM foo LEFT JOIN (select k || '' as k from lookup.lookyloo group by 1) l1 ON foo.dim1 = l1.k WHERE l1.k IS NOT NULL (in CalciteQueryTests)
In the current code, the WHERE clause gets removed from the top of the left join and is pushed to the table foo
leading to incorrect results.
The fix for such a situation is done by :
Converting such left joins into inner joins (since logically the mentioned left join query is equivalent to an inner join) using Calcite while maintaining that the druid execution layer can execute such inner joins.
Preferring converted inner joins over original left joins in our cost model
* Add a new metric query/segments/count that is not emitted by default
* docs
* test the default implementation of the metric
* fix spelling error in docs
* document the fact that query retries will result in additional metric emissions
* update using recommended text from @jihoonson
This PR refactors the code related to segment loading specifically SegmentLoader and SegmentLoaderLocalCacheManager. SegmentLoader is marked UnstableAPI which means, it can be extended outside core druid in custom extensions. Here is a summary of changes
SegmentLoader returns an instance of ReferenceCountingSegment instead of Segment. Earlier, SegmentManager was wrapping Segment objects inside ReferenceCountingSegment. That is now moved to SegmentLoader. With this, a custom implementation can track the references of segments. It also allows them to create custom ReferenceCountingSegment implementations. For this reason, the constructor visibility in ReferenceCountingSegment is changed from private to protected.
SegmentCacheManager has two additional methods called - reserve(DataSegment) and release(DataSegment). These methods let the caller reserve or release space without calling SegmentLoader#getSegment. We already had similar methods in StorageLocation and now they are available in SegmentCacheManager too which wraps multiple locations.
Refactoring to simplify the code in SegmentCacheManager wherever possible. There is no change in the functionality.

* Add back missing unit test coverage in AvroFlattenerMakerTest
Adds back test coverage for Avro flattener that was mistakenly removed in https://github.com/apache/druid/pull/10505. Recfactored the tests a bit too.
* resolve checkstyle warnings
This PR splits current SegmentLoader into SegmentLoader and SegmentCacheManager.
SegmentLoader - this class is responsible for building the segment object but does not expose any methods for downloading, cache space management, etc. Default implementation delegates the download operations to SegmentCacheManager and only contains the logic for building segments once downloaded. . This class will be used in SegmentManager to construct Segment objects.
SegmentCacheManager - this class manages the segment cache on the local disk. It fetches the segment files to the local disk, can clean up the cache, and in the future, support reserve and release on cache space. [See https://github.com/Make SegmentLoader extensible and customizable #11398]. This class will be used in ingestion tasks such as compaction, re-indexing where segment files need to be downloaded locally.
* add error messages in taskStatus for task failures in overlord
* unused imports
* add helper message for logs to look up
* fix tests
* fix counting the same task failures more than once
* same fix for HttpRemoteTaskRunner
The dependency-check cron job now purges any caches NVD before performing dependency check. Without this, a high CVE vulernability was reported in this job a few months after the nvd was updated for it.
Dependency on hadoop 2.8.5 is preventing us form updating this dependency to a later version. We don't believe that this is a major concern since Druid eats uncaught exceptions, and only displays them in logs. This issue also should only affect ingestion jobs, which can only be run by admin type users.
