Gian Merlino e0eb85ace7 Add FileUtils.createTempDir() and enforce its usage. (#8932)
* Add FileUtils.createTempDir() and enforce its usage.

The purpose of this is to improve error messages. Previously, the error
message on a nonexistent or unwritable temp directory would be
"Failed to create directory within 10,000 attempts".

* Further updates.

* Another update.

* Remove commons-io from benchmark.

* Fix tests.

Chi Cao Minh 8b2afa5c49 Use targetRowsPerSegment for single-dim partitions (#8624)
When using single-dimension partitioning, use targetRowsPerSegment (if
specified) to size segments. Previously, single-dimension partitioning
would always size segments as close to the max size as possible.

Also, change single-dimension partitioning to allow partitions that have
a size equal to the target or max size. Previously, it would create
partitions up to 1 less than those limits.

Also, fix some IntelliJ inspection warnings in HadoopDruidIndexerConfig.

Chi Cao Minh aeac0d4fd3 Adjust defaults for hashed partitioning (#8565)
* Adjust defaults for hashed partitioning

If neither the partition size nor the number of shards are specified,
default to partitions of 5,000,000 rows (similar to the behavior of
dynamic partitions). Previously, both could be null and cause incorrect
behavior.

Specifying both a partition size and a number of shards now results in
an error instead of ignoring the partition size in favor of using the
number of shards. This is a behavior change that makes it more apparent
to the user that only one of the two properties will be honored
(previously, a message was just logged when the specified partition size
was ignored).

* Fix test

* Handle -1 as null

* Add -1 as null tests for single dim partitioning

Chi Cao Minh 99b6eedab5 Rename partition spec fields (#8507)
* Rename partition spec fields

Rename partition spec fields to be consistent across the various types
(hashed, single_dim, dynamic). Specifically, use targetNumRowsPerSegment
and maxRowsPerSegment in favor of targetPartitionSize and
maxSegmentSize. Consistent and clearer names are easier for users to
understand and use.

Also fix various IntelliJ inspection warnings and doc spelling mistakes.

* Fix test

* Improve docs

* Add targetRowsPerSegment to HashedPartitionsSpec

Ankit Kothari 8492d94f59 Kill Hadoop MR task on kill of Hadoop ingestion task (#6828)
* KillTask from overlord UI now makes sure that it terminates the underlying MR job, thus saving unnecessary compute

Run in jobby is now split into 2
 1. submitAndGetHadoopJobId followed by 2. run
  submitAndGetHadoopJobId is responsible for submitting the job and returning the jobId as a string, run monitors this job for completion

JobHelper writes this jobId in the path provided by HadoopIndexTask which in turn is provided by the ForkingTaskRunner

HadoopIndexTask reads this path when kill task is clicked to get hte jobId and fire the kill command via the yarn api. This is taken care in the stopGracefully method which is called in SingleTaskBackgroundRunner. Have enabled `canRestore` method to return `true` for HadoopIndexTask in order for the stopGracefully method to be called

Hadoop*Job files have been changed to incorporate the changes to jobby

* Addressing PR comments

* Addressing PR comments - Fix taskDir

* Addressing PR comments - For changing the contract of Task.stopGracefully()

This PR accumulates many refactorings and small improvements that I did while preparing the next change set of https://github.com/druid-io/druid/projects/2. I finally decided to make them a separate PR to minimize the volume of the main PR.

Some of the changes:
 - Renamed confusing "Generic Column" term to "Numeric Column" (what it actually implies) in many class names.
 - Generified `ComplexMetricExtractor`

Gian Merlino 29af9f452a Fix for when Hadoop dataSource inputSpec is specified multiple times. (#5790)
This feature was introduced in #5717 but it didn't work in production
because this magical rewriter code wasn't also modified. Now, it is.

VersionedIntervalTimeline: Optimize construction with heavily populated holders. (#5777)
* VersionedIntervalTimeline: Optimize construction with heavily populated holders.

Each time a segment is "add"ed to a timeline, "isComplete" is called on the holder
that it is added to. "isComplete" is an O(segments per chunk) operation, meaning
that adding N segments to a chunk is an O(N^2) operation. This blows up badly if
we have thousands of segments per chunk.

The patch defers the "isComplete" check until after all segments have been
inserted.

* Fix imports.

Surekha 13c616ba24 'maxBytesInMemory' tuningConfig introduced for ingestion tasks (#5583)
* This commit introduces a new tuning config called 'maxBytesInMemory' for ingestion tasks

Currently a config called 'maxRowsInMemory' is present which affects how much memory gets
used for indexing.If this value is not optimal for your JVM heap size, it could lead
to OutOfMemoryError sometimes. A lower value will lead to frequent persists which might
be bad for query performance and a higher value will limit number of persists but require
more jvm heap space and could lead to OOM.
'maxBytesInMemory' is an attempt to solve this problem. It limits the total number of bytes
kept in memory before persisting.

 * The default value is 1/3(Runtime.maxMemory())
 * To maintain the current behaviour set 'maxBytesInMemory' to -1
 * If both 'maxRowsInMemory' and 'maxBytesInMemory' are present, both of them
   will be respected i.e. the first one to go above threshold will trigger persist

processing job.

The "expression" fields use the same expression language as other
expression-based feature.

Gian Merlino 1f2afccdf8 Expressions: Add ExprMacros. (#4365)
* Expressions: Add ExprMacros, which have the same syntax as functions, but
can convert themselves to any kind of Expr at parse-time.

ExprMacroTable is an extension point for adding new ExprMacros. Anything
that might need to parse expressions needs an ExprMacroTable, which can
be injected through Guice.

Gian Merlino b4289c0004 Remove "granularity" from IngestSegmentFirehose. (#4110)
It wasn't doing anything useful (the sequences were being concatted, and
cursor.getTime() wasn't being called) and it defaulted to Granularities.NONE.
Changing it to Granularities.ALL gave me a 700x+ performance boost on a
small dataset I was reindexing (2m27s to 365ms). Most of that was from avoiding
making a lot of unnecessary column selectors.

* Add virtual column types, holder serde, and safety features.

Virtual columns:

- put cache IDs in VirtualColumnCacheHelper
- adjust serde so VirtualColumns can be the holder object for Jackson
- add fail-fast validation for cycle detection and duplicates

  when a new base column is added that happens to have the same name as a
  virtual column.

* Fix ExtractionDimensionSpecs with virtual dimensions.

* Fix unused imports.

* CR comments

Erik Dubbelboer c0c34f82ad Fix reindexing of segments in Google Cloud Storage (#3788)
Google Cloud Storage allows `:` in paths. For this reason `google` was
not added to da007ca3c2/indexing-hadoop/src/main/java/io/druid/indexer/JobHelper.java (L585)
Normally this is not an issue but when reindexing segments the Hadoop
code for `getSplits` trips up on the `:` and returns:
`Relative path in absolute URI`
This patch URL encodes the `:` character making it work in Hadoop as
well.
