* Various documentation updates.
1) Split out "data management" from "ingestion". Break it into thematic pages.
2) Move "SQL-based ingestion" into the Ingestion category. Adjust content so
all conceptual content is in concepts.md and all syntax content is in reference.md.
Shorten the known issues page to the most interesting ones.
3) Add SQL-based ingestion to the ingestion method comparison page. Remove the
index task, since index_parallel is just as good when maxNumConcurrentSubTasks: 1.
4) Rename various mentions of "Druid console" to "web console".
5) Add additional information to ingestion/partitioning.md.
6) Remove a mention of Tranquility.
7) Remove a note about upgrading to Druid 0.10.1.
8) Remove no-longer-relevant task types from ingestion/tasks.md.
9) Move ingestion/native-batch-firehose.md to the hidden section. It was previously deprecated.
10) Move ingestion/native-batch-simple-task.md to the hidden section. It is still linked in some
places, but it isn't very useful compared to index_parallel, so it shouldn't take up space
in the sidebar.
11) Make all br tags self-closing.
12) Certain other cosmetic changes.
13) Update to node-sass 7.

This commit fixes issues with delayed supervisor termination during certain transient states.
Tasks can be created during supervisor termination and left behind since the cleanup may
not consider these newly added tasks.
#12178 added a lock for the entire process of task creation to prevent such dangling tasks.
But it also introduced a deadlock scenario as follows:
- An invocation of `runInternal` is in progress.
- A `stop` request comes, acquires `stateChangeLock` and submit a `ShutdownNotice`
- `runInternal` keeps waiting to acquire the `stateChangeLock`
- `ShutdownNotice` remains stuck in the notice queue because `runInternal` is still running
- After some timeout, the supervisor goes through a forced termination
Fix:
* `SeekableStreamSupervisor.runInternal` - do not try to acquire lock if supervisor is already stopping
* `SupervisorStateManager.maybeSetState` - do not allow transitions from STOPPING state
* Move web-console dependency from druid-server to distribution
* Add a test to check if the web-console is correctly integrated
* exclude web-console from 'other integration tests'
* Revert "exclude web-console from 'other integration tests'"
This reverts commit 8d72225544.
* Revert "Add a test to check if the web-console is correctly integrated"
This reverts commit d6ac8f3087.
* Update Snappy to 1.1.8.4.
Prior to this, because snappy-java wasn't included in dependencyManagement,
we actually shipped multiple different versions for different extensions,
ranging from 1.1.7.1 to 1.1.8.4. Now, we standardize on 1.1.8.4.
Among other things, this enables the tests to pass on M1 Macs.
* Update snappy-java versions in licenses.yaml.
1. remove unnecessary generic type from CompressedBigDecimal
2. support Number input types
3. support aggregator reading supported input types directly (uningested
data)
4. fix scaling bug in buffer aggregator
* SQL: Fix round-trips of floating point literals.
When writing RexLiterals into Druid expressions, we now write non-integer
numeric literals in such a way that ensures they are parsed as doubles
on the other end.
* Updates from code review, and some additional stuff inspired by the
investigation.
- Remove unnecessary formatting code from DruidExpression.doubleLiteral:
it handles things just fine with its default behavior.
- Fix a problem where expression literals could not represent Long.MIN_VALUE.
Now, integer literals start life off as BigIntegerExpr instead of LongExpr,
and are converted to LongExpr during flattening. This is necessary because,
in order to avoid ambiguity between unary minus and negative literals, our
grammar does not actually have true negative literals. Negative numbers must
be represented as unary minus next to a positive literal.
- Fix a bug introduced in #12230 where shuttle.visitAll(args) delegated
to shuttle.visit(arg) instead of arg.visit(shuttle). The latter does
a recursive visitation, which is the intended behavior.
* Style fixes.
* Move regexp to the right place.
* Cleaner JSON for various input sources and formats.
Add JsonInclude to various properties, to avoid population of default
values in serialized JSON.
Also fixes a bug in OrcInputFormat: it was not writing binaryAsString,
so the property would be lost on serde.
* Additonal test cases.
* Expose HTTP Response headers from SqlResource
This change makes the SqlResource expose HTTP response
headers in the same way that the QueryResource exposes them.
Fundamentally, the change is to pipe the QueryResponse
object all the way through to the Resource so that it can
populate response headers. There is also some code
cleanup around DI, as there was a superfluous FactoryFactory
class muddying things up.

changes:
* long and double value columns are now written directly, at the same time as writing out the 'intermediary' dictionaryid column with unsorted ids
* remove reverse value lookup from GlobalDictionaryIdLookup since it is no longer needed
* fix bug in /status/properties filtering
* Refactor tests to use jackson for parsing druid.server.hiddenProperties instead of hacky string modifications
* make javadoc more descriptive using example
* add in a sanity assertion that raw properties keyset size is greater than filtered properties keyset size
* MSQ extension: Fix over-capacity write in ScanQueryFrameProcessor.
Frame processors are meant to write only one output frame per cycle.
The ScanQueryFrameProcessor would write two when reading from a channel
if the input frame cursor cycled and then the output frame filled up
while reading from the next frame.
This patch fixes the bug, and adds a test. It also makes some adjustments
to the processor code in order to make it easier to test.
* Add license header.
* Add interpolation to JsonConfigurator
* Fix checkstyle
* Fix tests by removing common-text override
* Add back commons-text without version
* Remove unused hadoopDir configs
* Move some stuff to hopefully pass coverage
* more consistent expression error messages
* review stuff
* add NamedFunction for Function, ApplyFunction, and ExprMacro to share common stuff
* fixes
* add expression transform name to transformer failure, better parse_json error messaging
-Add classes for writing cell values in LZ4 block compressed format.
Payloads are indexed by element number for efficient random lookup
-update SerializablePairLongStringComplexMetricSerde to use block
compression
-SerializablePairLongStringComplexMetricSerde also uses delta encoding
of the Long by doing 2-pass encoding: buffers first to find min/max
numbers and delta-encodes as integers if possible
Entry points for doing block-compressed storage of byte[] payloads
are the CellWriter and CellReader class. See
SerializablePairLongStringComplexMetricSerde for how these are used
along with how to do full column-based storage (delta encoding here)
which includes 2-pass encoding to compute a column header
