Surekha 8619adb5b9 Improve task retrieval APIs on Overlord (#5801)
* Add the new tasks api in overlordResource

It takes 4 optional query params
* state(pending/running/waiting/compelte)
* dataSource
* interval (applies to completed tasks)
* maxCompletedTasks (applies to completed tasks)

If all params are null, the api returns all the tasks

* Add the state to each task returned by tasks endpoint

* divide active tasks into waiting, pending or running
* Add more unit tests

* Add UNKNOWN state to TaskState

* Fix the authorization calls

* WIP: PR comments

Added new class to capture task info for caching
Other refactoring

* Refactoring : move TaskStatus class to druid-api

so it can be accessed within server
And other related classes like TaskState and TaskStatusPlus are in api

* Remove unused class and apis accessing it

* Add a separate cache for recently completed tasks

This is to mainly capture the task type from payload

* Ignore a test

* Add a RuntimeTaskState to encompass all states a task can be in

* Revert "Add a RuntimeTaskState to encompass all states a task can be in"

Gian Merlino 0ae4aba4e2 HdfsDataSegmentPusher: Close tmpIndexFile before copying it. (#5873)
It seems that copy-before-close works OK on HDFS, but it doesn't work
on all filesystems. In particular, we observed this not working properly
with Google Cloud Storage. And anyway, it's better hygiene to close files
before attempting to copy them somewhere else.

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

bolkedebruin 8f07a39af7 Skip OS cache on Linux when pulling segments (#5421)
Druid relies on the page cache of Linux in order to have memory segments.
However when loading segments from deep storage or rebalancing the page
cache can get poisoned by segments that should not be in memory yet.
This can significantly slow down Druid in case rebalancing happens
as data that might not be queried often is suddenly in the page cache.

This PR implements the same logic as is in Apache Cassandra and Apache
Bookkeeper.

Closes #4746

Nishant Bangarwa e0d456b1ba Uniformly set Calcite systemProperties for All Unit tests (#5451)
Fixes test failures reported in -
https://github.com/druid-io/druid/issues/4909

Issue is that If some test skips setting up Calcite system properties
with proper encoding and loads calcite classes that use that property,
All subsequent tests in the same JVM fails.

To reproduce the issue - ExpressionsTest and CalciteQueryTest from IDE
in this order.

A better fix would be to not use System Properties in calcite, This
will work for now.

All new Calcite Unit tests that are added need to inherit
CalciteTestBase.
