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

* 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.

Users sometimes make typos when picking timezones - like `America/Los Angeles`
instead of `America/Los_Angeles` instead of defaulting to UTC, this change
makes it so that an error is thrown instead notifying the user of their mistake.

remove real time flag stuff from stream appenderator, etc.)

A constant expression may evaluate to Double.NEGATIVE_INFINITY/Double.POSITIVE_INFINITY/Double.NAN e.g. log10(0). When using such an expression in native queries, the user will get the corresponding value without any error. In SQL, however, the user will run into NumberFormatException because we convert the double to big-decimal while constructing a literal numeric expression. This probably should be fixed in calcite - see https://issues.apache.org/jira/browse/CALCITE-2067. This PR adds a verbose error message so that users can take corrective action without scratching their heads.

Quote the $java_exec var in examples/bin/verify-java to support spaces in DRUID_JAVA_HOME/JAVA_HOME. At present, the steps before and after the version check properly quote the path, but the version check spuriously fails when pointing to a Java 8 install that has a space in its path.

* Fix expiration logic for ldap internal credential cache
* Removed sleeps from tests
* Make method package scoped so it can be used in unit tests
* Removed unused thrown exceptions
This PR refactors the code for QueryRunnerFactory#mergeRunners to accept a new interface called QueryProcessingPool instead of ExecutorService for concurrent execution of query runners. This interface will let custom extensions inject their own implementation for deciding which query-runner to prioritize first. The default implementation is the same as today that takes the priority of query into account. QueryProcessingPool can also be used as a regular executor service. It has a dedicated method for accepting query execution work so implementations can differentiate between regular async tasks and query execution tasks. This dedicated method also passes the QueryRunner object as part of the task information. This hook will let custom extensions carry any state from QuerySegmentWalker to QueryProcessingPool#mergeRunners which is not possible currently.

* break out component
* fix test
* update test script

In some instances the ingestion thread could be woken up spuriously,
resulting in the "Received pause command..." log message getting logged
multiple times. This change ensures we only log it once the first time
the pause is requested.
* tidy up
* add to segments view
* add unit tests for date
* better util export
* fix ds view
* fix tests
* fix test in time
* unset untermediate state
Switching to the bom dependency declaration simplifies managing jackson
dependencies. It also removes the need to override individual library
versions for CVE fixes, since the bom takes care of that internally.
This change aligns our jackson dependency versions on 2.10.5(.x):
- updates jackson libraries from 2.10.2 to 2.10.5
- jackson-databind remains at 2.10.5.1 as defined in the bom
Release notes: https://github.com/FasterXML/jackson/wiki/Jackson-Release-2.10
