Change Kafka Lookup Extractor to not register consumer group (#12842)
* change kafka lookups module to not commit offsets

The current behaviour of the Kafka lookup extractor is to not commit
offsets by assigning a unique ID to the consumer group and setting
auto.offset.reset to earliest. This does the job but also pollutes the
Kafka broker with a bunch of "ghost" consumer groups that will never again be
used.

To fix this, we now set enable.auto.commit to false, which prevents the
ghost consumer groups being created in the first place.

* update docs to include new enable.auto.commit setting behaviour

* update kafka-lookup-extractor documentation

Provide some additional detail on functionality and configuration.
Hopefully this will make it clearer how the extractor works for
developers who aren't so familiar with Kafka.

* add comments better explaining the logic of the code

* add spelling exceptions for kafka lookup docs

Improved Java 17 support and Java runtime docs. (#12839)
* Improved Java 17 support and Java runtime docs.

1) Add a "Java runtime" doc page with information about supported
   Java versions, garbage collection, and strong encapsulation..

2) Update asm and equalsverifier to versions that support Java 17.

3) Add additional "--add-opens" lines to surefire configuration, so
   tests can pass successfully under Java 17.

4) Switch openjdk15 tests to openjdk17.

5) Update FrameFile to specifically mention Java runtime incompatibility
   as the cause of not being able to use Memory.map.

6) Update SegmentLoadDropHandler to log an error for Errors too, not
   just Exceptions. This is important because an IllegalAccessError is
   encountered when the correct "--add-opens" line is not provided,
   which would otherwise be silently ignored.

7) Update example configs to use druid.indexer.runner.javaOptsArray
   instead of druid.indexer.runner.javaOpts. (The latter is deprecated.)

* Adjustments.

* Use run-java in more places.

* Add run-java.

* Update .gitignore.

* Exclude hadoop-client-api.

Brought in when building on Java 17.

* Swap one more usage of java.

* Fix the run-java script.

* Fix flag.

* Include link to Temurin.

* Spelling.

* Update examples/bin/run-java

ConcurrentGrouper: Add mergeThreadLocal option, fix bug around the switch to spilling. (#12513)
* ConcurrentGrouper: Add option to always slice up merge buffers thread-locally.

Normally, the ConcurrentGrouper shares merge buffers across processing
threads until spilling starts, and then switches to a thread-local model.
This minimizes memory use and reduces likelihood of spilling, which is
good, but it creates thread contention. The new mergeThreadLocal option
causes a query to start in thread-local mode immediately, and allows us
to experiment with the relative performance of the two modes.

* Fix grammar in docs.

* Fix race in ConcurrentGrouper.

* Fix issue with timeouts.

* Remove unused import.

* Add "tradeoff" to dictionary.

SQL: Add is_active to sys.segments, update examples and docs. (#11550)
* SQL: Add is_active to sys.segments, update examples and docs.

is_active is short for:

  (is_published = 1 AND is_overshadowed = 0) OR is_realtime = 1

It's important because this represents "all the segments that should
be queryable, whether or not they actually are right now". Most of the
time, this is the set of segments that people will want to look at.

The web console already adds this filter to a lot of its queries,
proving its usefulness.

This patch also reworks the caveat at the bottom of the sys.segments
section, so its information is mixed into the description of each result
field. This should make it more likely for people to see the information.

* Wording updates.

* Adjustments for spellcheck.

* Adjust IT.

Enforce console logging for peon process (#12067)
Currently all Druid processes share the same log4j2 configuration file located in _common directory. Since peon processes are spawned by middle manager process, they derivate the environment variables from the middle manager. These variables include those in the log4j2.xml controlling to which file the logger writes the log.

But current task logging mechanism requires the peon processes to output the log to console so that the middle manager can redirect the console output to a file and upload this file to task log storage.

So, this PR imposes this requirement to peon processes, whatever the configuration is in the shared log4j2.xml, peon processes always write the log to console.

Add setProcessingThreadNames context parameter. (#12514)
setting thread names takes a measurable amount of time in the case where segment scans are very quick. In high-QPS testing we found a slight performance boost from turning off processing thread renaming. This option makes that possible.

Allow coordinator to be configured to kill segments in future (#10877)
Allow a Druid cluster to kill segments whose interval_end is a date in the future. This can be done by setting druid.coordinator.kill.durationToRetain to a negative period. For example PT-24H would allow segments to be killed if their interval_end date was 24 hours or less into the future at the time that the kill task is generated by the system.

A cluster operator can also disregard the druid.coordinator.kill.durationToRetain entirely by setting a new configuration, druid.coordinator.kill.ignoreDurationToRetain=true. This ignores interval_end date when looking for segments to kill, and instead is capable of killing any segment marked unused. This new configuration is off by default, and a cluster operator should fully understand and accept the risks if they enable it.

GroupBy: Cap dictionary-building selector memory usage. (#12309)
* GroupBy: Cap dictionary-building selector memory usage.

New context parameter "maxSelectorDictionarySize" controls when the
per-segment processing code should return early and trigger a trip
to the merge buffer.

Includes:

- Vectorized and nonvectorized implementations.
- Adjustments to GroupByQueryRunnerTest to exercise this code in
  the v2SmallDictionary suite. (Both the selector dictionary and
  the merging dictionary will be small in that suite.)
- Tests for the new config parameter.

* Fix issues from tests.

* Add "pre-existing" to dictionary.

* Simplify GroupByColumnSelectorStrategy interface by removing one of the writeToKeyBuffer methods.

* Adjustments from review comments.

Adding new config for disabling group by on multiValue column (#12253)
As part of #12078 one of the followup's was to have a specific config which does not allow accidental unnesting of multi value columns if such columns become part of the grouping key.
Added a config groupByEnableMultiValueUnnesting which can be set in the query context.

The default value of groupByEnableMultiValueUnnesting is true, therefore it does not change the current engine behavior.
If groupByEnableMultiValueUnnesting is set to false, the query will fail if it encounters a multi-value column in the grouping key.

Support for hadoop 3 via maven profiles (#11794)
Add support for hadoop 3 profiles . Most of the details are captured in #11791 .
We use a combination of maven profiles and resource filtering to achieve this. Hadoop2 is supported by default and a new maven profile with the name hadoop3 is created. This will allow the user to choose the profile which is best suited for the use case.

Add druid.sql.approxCountDistinct.function property. (#11181)
* Add druid.sql.approxCountDistinct.function property.

The new property allows admins to configure the implementation for
APPROX_COUNT_DISTINCT and COUNT(DISTINCT expr) in approximate mode.

The motivation for adding this setting is to enable site admins to
switch the default HLL implementation to DataSketches.

For example, an admin can set:

  druid.sql.approxCountDistinct.function = APPROX_COUNT_DISTINCT_DS_HLL

* Fixes

* Fix tests.

Kafka Input Format for headers, key and payload parsing (#11630)
### Description

Today we ingest a number of high cardinality metrics into Druid across dimensions. These metrics are rolled up on a per minute basis, and are very useful when looking at metrics on a partition or client basis. Events is another class of data that provides useful information about a particular incident/scenario inside a Kafka cluster. Events themselves are carried inside kafka payload, but nonetheless there are some very useful metadata that is carried in kafka headers that can serve as useful dimension for aggregation and in turn bringing better insights.

PR(https://github.com/apache/druid/pull/10730) introduced support of Kafka headers in InputFormats.

We still need an input format to parse out the headers and translate those into relevant columns in Druid. Until that’s implemented, none of the information available in the Kafka message headers would be exposed. So first there is a need to write an input format that can parse headers in any given format(provided we support the format) like we parse payloads today. Apart from headers there is also some useful information present in the key portion of the kafka record. We also need a way to expose the data present in the key as druid columns. We need a generic way to express at configuration time what attributes from headers, key and payload need to be ingested into druid. We need to keep the design generic enough so that users can specify different parsers for headers, key and payload.

This PR is designed to solve the above by providing wrapper around any existing input formats and merging the data into a single unified Druid row.

Lets look at a sample input format from the above discussion

"inputFormat":
{
    "type": "kafka",     // New input format type
    "headerLabelPrefix": "kafka.header.",   // Label prefix for header columns, this will avoid collusions while merging columns
    "recordTimestampLabelPrefix": "kafka.",  // Kafka record's timestamp is made available in case payload does not carry timestamp
    "headerFormat":  // Header parser specifying that values are of type string
    {
        "type": "string"
    },
    "valueFormat": // Value parser from json parsing
    {
        "type": "json",
        "flattenSpec": {
          "useFieldDiscovery": true,
          "fields": [...]
        }
    },
    "keyFormat":  // Key parser also from json parsing
    {
        "type": "json"
    }
}

Since we have independent sections for header, key and payload, it will enable parsing each section with its own parser, eg., headers coming in as string and payload as json. 

KafkaInputFormat will be the uber class extending inputFormat interface and will be responsible for creating individual parsers for header, key and payload, blend the data resolving conflicts in columns and generating a single unified InputRow for Druid ingestion. 

"headerFormat" will allow users to plug parser type for the header values and will add default header prefix as "kafka.header."(can be overridden) for attributes to avoid collision while merging attributes with payload.

Kafka payload parser will be responsible for parsing the Value portion of the Kafka record. This is where most of the data will come from and we should be able to plugin existing parser. One thing to note here is that if batching is performed, then the code is augmenting header and key values to every record in the batch.

Kafka key parser will handle parsing Key portion of the Kafka record and will ingest the Key with dimension name as "kafka.key".

## KafkaInputFormat Class: 
This is the class that orchestrates sending the consumerRecord to each parser, retrieve rows, merge the columns into one final row for Druid consumption. KafkaInputformat should make sure to release the resources that gets allocated as a part of reader in CloseableIterator<InputRow> during normal and exception cases.

During conflicts in dimension/metrics names, the code will prefer dimension names from payload and ignore the dimension either from headers/key. This is done so that existing input formats can be easily migrated to this new format without worrying about losing information.

DruidInputSource: Fix issues in column projection, timestamp handling. (#10267)
* DruidInputSource: Fix issues in column projection, timestamp handling.

DruidInputSource, DruidSegmentReader changes:

1) Remove "dimensions" and "metrics". They are not necessary, because we
   can compute which columns we need to read based on what is going to
   be used by the timestamp, transform, dimensions, and metrics.
2) Start using ColumnsFilter (see below) to decide which columns we need
   to read.
3) Actually respect the "timestampSpec". Previously, it was ignored, and
   the timestamp of the returned InputRows was set to the `__time` column
   of the input datasource.

(1) and (2) together fix a bug in which the DruidInputSource would not
properly read columns that are used as inputs to a transformSpec.

(3) fixes a bug where the timestampSpec would be ignored if you attempted
to set the column to something other than `__time`.

(1) and (3) are breaking changes.

Web console changes:

1) Remove "Dimensions" and "Metrics" from the Druid input source.
2) Set timestampSpec to `{"column": "__time", "format": "millis"}` for
   compatibility with the new behavior.

Other changes:

1) Add ColumnsFilter, a new class that allows input readers to determine
   which columns they need to read. Currently, it's only used by the
   DruidInputSource, but it could be used by other columnar input sources
   in the future.
2) Add a ColumnsFilter to InputRowSchema.
3) Remove the metric names from InputRowSchema (they were unused).
4) Add InputRowSchemas.fromDataSchema method that computes the proper
   ColumnsFilter for given timestamp, dimensions, transform, and metrics.
5) Add "getRequiredColumns" method to TransformSpec to support the above.
