fix task metric types in statsd emitter ()
except success and failure stats, task count metrics should all be
gauges, since they represent the current state and not some aggregate
counter over time.

Two fixes related to encoding of % symbols. ()
* Two fixes related to encoding of % symbols.

1) TaskResourceFilter: Don't double-decode task ids. request.getPathSegments()
   returns already-decoded strings. Applying StringUtils.urlDecode on
   top of that causes erroneous behavior with '%' characters.

2) Update various ThreadFactoryBuilder name formats to escape '%'
   characters. This fixes situations where substrings starting with '%'
   are erroneously treated as format specifiers.

ITs are updated to include a '%' in extra.datasource.name.suffix.

* Avoid String.replace.

* Work around surefire bug.

* Fix xml encoding.

* Another try at the proper encoding.

* Give up on the emojis.

* Less ambitious testing.

* Fix an additional problem.

* Adjust encodeForFormat to return null if the input is null.

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

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

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.

  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.

- 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.

Add config option for namespacePrefix ()
* 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

* Spelling for PR 

Added "namespacePrefix" to .spelling exceptions, it's a variable name
used in documentation for opentsdb-emitter.

* fixing tests for PR 

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 

used == to compare literal string, should be equals()

* cleaned up and updated PR 

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 

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. ()
Builds on , 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  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. ()
* 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. ()
* GroupBy array-based result rows.

Fixes ; 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.
