Broker: Add ability to inline subqueries. (#9533)
* Broker: Add ability to inline subqueries.

The main changes:

- ClientQuerySegmentWalker: Add ability to inline queries.
- Query: Add "getSubQueryId" and "withSubQueryId" methods.
- QueryMetrics: Add "subQueryId" dimension.
- ServerConfig: Add new "maxSubqueryRows" parameter, which is used by
  ClientQuerySegmentWalker to limit how many rows can be inlined per
  query.
- IndexedTableJoinMatcher: Allow creating keys on top of unknown types,
  by assuming they are strings. This is useful because not all types are
  known for fields in query results.
- InlineDataSource: Store RowSignature rather than component parts. Add
  more zealous "equals" and "hashCode" methods to ease testing.
- Moved QuerySegmentWalker test code from CalciteTests and
  SpecificSegmentsQueryWalker in druid-sql to QueryStackTests in
  druid-server. Use this to spin up a new ClientQuerySegmentWalkerTest.

* Adjustments from CI.

* Fix integration test.

Move RowSignature from druid-sql to druid-processing and make use of it. (#9508)
* Move RowSignature from druid-sql to druid-processing and make use of it.

1) Moved (most of) RowSignature from sql to processing. Left behind the SQL-specific
   stuff in a RowSignatures utility class. It also picked up some new convenience
   methods along the way.
2) There were a lot of places in the code where Map<String, ValueType> was used to
   associate columns with type info. These are now all replaced with RowSignature.
3) QueryToolChest's resultArrayFields method is replaced with resultArraySignature,
   and it now provides type info.

* Fix up extensions.

* Various fixes

Link up row-based datasources to serving layer. (#9503)
* Link up row-based datasources to serving layer.

- Add SegmentWrangler interface that allows linking of DataSources to Segments.
- Add LocalQuerySegmentWalker that uses SegmentWranglers to compute queries on
  data that is available locally.
- Modify ClientQuerySegmentWalker to use LocalQuerySegmentWalker when the base
  datasource is concrete and not a table.
- Add SegmentWranglerModule to the Broker so it has them available and can
  properly instantiate . LocalQuerySegmentWalkers.
- Set InlineDataSource and LookupDataSource to concrete, since they can be
  directly queried now.

* Fix tests.

Harmonization and bug-fixing for selector and filter behavior on unknown types. (#9484)
* Harmonization and bug-fixing for selector and filter behavior on unknown types.

- Migrate ValueMatcherColumnSelectorStrategy to newer ColumnProcessorFactory
  system, and set defaultType COMPLEX so unknown types can be dynamically matched.
- Remove ValueGetters in favor of ColumnComparisonFilter doing its own thing.
- Switch various methods to use convertObjectToX when casting to numbers, rather
  than ad-hoc and inconsistent logic.
- Fix bug in RowBasedExpressionColumnValueSelector: isBindingArray should return
  true even for 0- or 1- element arrays.
- Adjust various javadocs.

* Add throwParseExceptions option to Rows.objectToNumber, switch back to that.

* Update tests.

* Adjust moment sketch tests.

Add config option for namespacePrefix (#9372)
* 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.

Use DataSourceAnalysis throughout the query stack. (#9239)
Builds on #9235, using the datasource analysis functionality to replace various ad-hoc
approaches. The most interesting changes are in ClientQuerySegmentWalker (brokers),
ServerManager (historicals), and SinkQuerySegmentWalker (indexing tasks).

Other changes related to improving how we analyze queries:

1) Changes TimelineServerView to return an Optional timeline, which I thought made
   the analysis changes cleaner to implement.
2) Added QueryToolChest#canPerformSubquery, which is now used by query entry points to
   determine whether it is safe to pass a subquery dataSource to the query toolchest.
   Fixes an issue introduced in #5471 where subqueries under non-groupBy-typed queries
   were silently ignored, since neither the query entry point nor the toolchest did
   anything special with them.
3) Removes the QueryPlus.withQuerySegmentSpec method, which was mostly being used in
   error-prone ways (ignoring any potential subqueries, and not verifying that the
   underlying data source is actually a table). Replaces with a new function,
   Queries.withSpecificSegments, that includes sanity checks.

* Address security vulnerabilities CVSS >= 7

Update dependencies to address security vulnerabilities with CVSS scores
of 7 or higher. A new Travis CI job is added to prevent new
high/critical security vulnerabilities from being added.

Updated dependencies:
- api-util 1.0.0 -> 1.0.3
- jackson 2.9.10 -> 2.10.1
- kafka 2.1.0 -> 2.1.1
- libthrift 0.10.0 -> 0.13.0
- protobuf 3.2.0 -> 3.11.0

The following high/critical security vulnerabilities are currently
suppressed (so that the new Travis CI job can be added now) and are left
as future work to fix:
- hibernate-validator:5.2.5
- jackson-mapper-asl:1.9.13
- libthrift:0.6.1
- netty:3.10.6
- nimbus-jose-jwt:4.41.1

Gian Merlino c44452f0c1 Tidy up lifecycle, query, and ingestion logging. (#8889)
* Tidy up lifecycle, query, and ingestion logging.

The goal of this patch is to improve the clarity and usefulness of
Druid's logging for cluster operators. For more information, see
https://twitter.com/cowtowncoder/status/1195469299814555648.

Concretely, this patch does the following:

- Changes a lot of INFO logs to DEBUG, and DEBUG to TRACE, with the
  goal of reducing redundancy and improving clarity by avoiding
  showing rarely-useful log messages. This includes most "starting"
  and "stopping" messages, and most messages related to individual
  columns.
- Adds new log4j2 templates that show operators how to enabled DEBUG
  logging for certain important packages.
- Eliminate stack traces for query errors, unless log level is DEBUG
  or more. This is useful because query errors often indicate user
  error rather than system error, but dumping stack trace often gave
  operators the impression that there was a system failure.
- Adds task id to Appenderator, AppenderatorDriver thread names. In
  the default log4j2 configuration, this will put them in log lines
  as well. It's very useful if a user is using the Indexer, where
  multiple tasks run in the same JVM.
- More consistent terminology when it comes to "sequences" (sets of
  segments that are handed-off together by Kafka ingestion) and
  "offsets" (cursors in partitions). These terms had been confused in
  some log messages due to the fact that Kinesis calls offsets
  "sequence numbers".
- Replaces some ugly toString calls with either the JSONification or
  something more operator-accessible (like a URL or segment identifier,
  instead of JSON object representing the same).

* Adjustments.

* Adjust integration test.

Gian Merlino 77297f4e6f GroupBy array-based result rows. (#8196)
* GroupBy array-based result rows.

Fixes #8118; see that proposal for details.

Other than the GroupBy changes, the main other "interesting" classes are:

- ResultRow: The array-based result type.
- BaseQuery: T is no longer required to be Comparable.
- QueryToolChest: Adds "decorateObjectMapper" to enable query-aware serialization
  and deserialization of result rows (necessary due to their positional nature).
- QueryResource: Uses the new decoration functionality.
- DirectDruidClient: Also uses the new decoration functionality.
- QueryMaker (in Druid SQL): Modifications to read ResultRows.

These classes weren't changed, but got some new javadocs:

- BySegmentQueryRunner
- FinalizeResultsQueryRunner
- Query

Xavier Léauté 484afe0afb exclude hadoop system dependency
ambari depends on hadoop-annotation. Under linux, it sometimes activates a
maven profile that includes an explicit dependency on ${java.home}/../lib/tools.jar

This change excludes this dependency, since this jar is no longer
included with Java 9. It also seems seems unlikely that we would require
this dependency at runtime, since it is only enabled on some platforms.

com.puppycrawl.tools:checkstyle

Checkstyle prior to 8.18 loads external DTDs by default,
which can potentially lead to denial of service attacks
or the leaking of confidential information.

Affected versions: < 8.18

This is an extension of PR #5750 by @drcrallen which added retry to a variety of

occasionally fail in our cluster.

Also fixes a typo in a variable name and removes an unused private method
parameter.

David Glasser c08f391605 statsd-emitter: support constant DogStatsD tags (#6791)
PR #6605 added support to the statsd emitter for DogStatsD tags. This commit
lets you specify "constant tags" in the config file which are included with
every event. This is helpful if you are running in an environment where you
cannot configure your datadog-agent with tags like "cluster name" --- eg, a
Kubernetes cluster with a datadog-agent on each node and different Druid
deployments in different namespaces but sharing the same datadog-agent
daemonset.

Also fix the name of an existing boolean getter to start with 'is'.

Deiwin Sarjas e0d1dc5846 Support DogStatsD style tags in statsd-emitter (#6605)
* Replace StatsD client library

The [Datadog package][1] is a StatsD compatible drop-in replacement for the
client library, but it seems to be [better maintained][2] and has support for
Datadog DogStatsD specific features, which will be made use of in a subsequent
commit.

The `count`, `time`, and `gauge` methods are actually exactly compatible with
the previous library and the modifications shouldn't be required, but EasyMock
seems to have a hard time dealing with the variable arguments added by the
DogStatsD library and causes tests to fail if no arguments are provided for the
last String vararg. Passing an empty array fixes the test failures.

[2]: https://github.com/tim-group/java-statsd-client/issues/37#issuecomment-248698856

* Retain dimension key information for StatsD metrics

This doesn't change behavior, but allows separating dimensions from the metric
name in subsequent commits.

There is a possible order change for values from
`dimsBuilder.build().values()`, but from the tests it looks like it doesn't
affect actual behavior and the order of user dimensions is also retained.

* Support DogStatsD style tags in statsd-emitter

Datadog [doesn't support name-encoded dimensions and uses a concept of _tags_
instead.][1] This change allows Datadog users to send the metrics without
having to encode the various dimensions in the metric names. This enables
building graphs and monitors with and without aggregation across various
dimensions from the same data.

As tests in this commit verify, the behavior remains the same for users who
don't enable the `druid.emitter.statsd.dogstatsd` configuration flag.

[1]: https://www.datadoghq.com/blog/the-power-of-tagged-metrics/#tags-decouple-collection-and-reporting

* Disable convertRange behavior for DogStatsD users

DogStatsD, unlike regular StatsD, supports floating-point values, so this
behavior is unnecessary. It would be possible to still support `convertRange`,
even with `dogstatsd` enabled, but that would mean that people using the
default mapping would have some of the gauges unnecessarily converted.

`time` is in milliseconds and doesn't support floating-point values.
