added a configuration option to allow the user to specify the
maximum number of input files to stream for each iteration.

CVE-2020-8840 was updated on 19 Feb 2020, which now gets flagged by the
security vulnerability scan. Since the CVE is for jackson-databind, via
htrace-core-4.0.1, it can be added to the existing list of security
vulnerability suppressions for that dependency.
* Add config option for namespacePrefix
opentsdb emitter sends metric names to opentsdb verbatim as what druid
names them, for example "query.count", this doesn't fit well with a
central opentsdb server which might have namespaced metrics, for example
"druid.query.count". This adds support for adding an optional prefix.
The prefix also gets a trailing dot (.), after it, so the metric name
becomes <namespacePrefix>.<metricname>
configureable as "druid.emitter.opentsdb.namespacePrefix", as
documented.

* Spelling for PR #9372
Added "namespacePrefix" to .spelling exceptions, it's a variable name
used in documentation for opentsdb-emitter.
* fixing tests for PR #9372
changed naming of variables to be more descriptive
added test of prefix being an empty string: "".
added a conditional to buildNamespacePrefix to check for empty string
being fed if EventConverter called without OpentsdbEmitterConfig
instance.
* fixing checkstyle errors for PR #9372
used == to compare literal string, should be equals()
* cleaned up and updated PR #9372
Created a buildMetric function as suggested by clintropolis, and
removed redundant tests for empty strings as they're only used when
calling EventConverter directly without going through
OpentsdbEmitterConfig.
* consistent naming of tests PR #9372
Changed names of tests in files to match better with what it was
actually testing
changed check for Strings.isNullOrEmpty to just check for `null`, as
empty string valued `namespacePrefix` is handled in
OpentsdbEmitterConfig.

* Make java version check work on all shells
Previously, "perl verify-java" would fail on shells like zsh, which
would cause the quickstart scripts (e.g., bin/start-micro-quickstart) to
fail unless the DRUID_SKIP_JAVA_SKIP environment variable is set.
* Support dash (ubuntu)
* Run IntelliJ inspections on Travis
Running IntelliJ inspections currently takes about 90 minutes, but they
can be run in about 30 minutes on Travis.
* Restore assert statements
* Remove references to Docker Machine
Removing a broken link to an obsolete repo.
While at it, removing references to Docker Machine, which was obsolete as of Docker v1.12 (avail. 2016). This version introduced Docker as native MacOS and Windows apps.
* Update README.md
Wording nit.
* Fix timestamp extract fn to match postgres
Update the timestamp extract function so that it matches the PostgreSQL docs.
Examples from the PostgreSQL docs were added as tests for DECADE, CENTURY
and MILLENIUM extraction.
There were bugs in CENTURY and MILLENIUM that were spotted because of intelliJ
inspections - 'Integer division in floating point context'
* Update CalciteQueryTest
* remove useless round
* mark integer division as an error
* Use ExecutorService instead of ScheduledExecutorService where necessary - #9286
* Added inspection rule to prohibit ScheduledExecutorService assignment to ExecutorService
* IMPLY-1946: Improve code quality and unit test coverage of the Azure extension

* * deprecate azure firehose
* * added more tests
* * rollback fix for google cloud batch ingestion bug. Will be
fixed in another PR.
* * Added javadocs for all azure related classes
* Addressed review comments
* * Remove dependency on org.apache.commons:commons-collections4
* Fix LGTM warnings
* Add com.google.inject.extensions:guice-assistedinject to licenses
* * rename classes as suggested in review comments
* * Address review comments
* * Address review comments

* Change security vulnerability scan to cron job
Previously, when new CVEs were reported, the security vulnerability scan
would unfortunately block PRs that did not modify any dependencies. To
prevent this issue, the security scan is now run as a Travis cron job
that runs on master and notifies the druid dev list if it fails. The
security scan has also been added to the "apache-release" maven profile,
to ensure that it passes before a release.
Also adjusted some Travis CI job failure help messages to not be folded
in the Travis CI job logs.
* Dedup plugin configuration definition
More functional tests to cover handling of input data that has a
partition dimension that contains:
1) Null values: Should be in first partition
2) Multi values: Should cause superbatch task to abort
When the time extraction Top N algorithm is looking for aggregators, it makes
2 calls to hashCode on the key. Use Map#computeIfAbsent instead so that the
hashCode is calculated only once
* Codestyle - use java style array declaration
Replaced C-style array declarations with java style declarations and marked
the intelliJ inspection as an error
* cleanup test code
* Refactoring codes around ingestion:
- Parallel index task and simple task now use the same segment allocator implementation. This is reusable for the future implementation as well.
- Added PartitionAnalysis to store the analysis of the partitioning
- Move some util methods to SegmentLockHelper and rename it to TaskLockHelper

2) Modifies BufferArrayGrouper to match the new VectorGrouper interface.
3) Removes "implements VectorGrouper" from BufferHashGrouper.

* Fix newline at end of configuration index.md
* Last try to resolve newline issue in configuration readme
* fix spell checks from travis build
* Fix another flagges spelling error from Travis
* Remove EasyMock dependency from CalciteTests.
Useful because CalciteTests is used by other modules (e.g. druid-benchmarks)
and we don't want them to have to pull in EasyMock.
* CalciteTests no longer needs curator-x-discovery either.
* Add MemoryOpenHashTable, a table similar to ByteBufferHashTable.
With some key differences to improve speed and design simplicity:
1) Uses Memory rather than ByteBuffer for its backing storage.
2) Uses faster hashing and comparison routines (see HashTableUtils).
3) Capacity is always a power of two, allowing simpler design and more
efficient implementation of findBucket.
4) Does not implement growability; instead, leaves that to its callers.
The idea is this removes the need for subclasses, while still giving
callers flexibility in how to handle table-full scenarios.
* Fix LGTM warnings.
* Adjust dependencies.
* Remove easymock from druid-benchmarks.
* Adjustments from review.
* Fix datasketches unit tests.
* Fix checkstyle.
* Speed up joins on indexed tables with string keys
When joining on index tables with string keys, caching the computation
of row id to row numbers improves performance on the
JoinAndLookupBenchmark.joinIndexTableStringKey* benchmarks by about 10%
if the column cache is enabled an by about 100% if the column cache is
disabled.
