- Made FileSystemBasedLockProviderTestClass thread safe and fixed the
tryLock retry logic.
- Made TestHoodieClientMultiWriter. testHoodieClientBasicMultiWriter
deterministic in verifying the HoodieWriteConflictException.
* [HUDI-2923] Fixing metadata table reader when metadata compaction is inflight
* Fixing retry of pending compaction in metadata table and enhancing tests
- Changes the default config of marker type (HoodieWriteConfig.MARKERS_TYPE or hoodie.write.markers.type) from DIRECT to TIMELINE_SERVER_BASED for Spark Engine.
- Adds engine-specific marker type configs: Spark -> TIMELINE_SERVER_BASED, Flink -> DIRECT, Java -> DIRECT.
- Uses DIRECT markers as well for Spark structured streaming due to timeline server only available for the first mini-batch.
- Fixes the marker creation method for non-partitioned table in TimelineServerBasedWriteMarkers.
- Adds the fallback to direct markers even when TIMELINE_SERVER_BASED is configured, in WriteMarkersFactory: when HDFS is used, or embedded timeline server is disabled, the fallback to direct markers happens.
- Fixes the closing of timeline service.
- Fixes tests that depend on markers, mainly by starting the timeline service for each test.

* [HUDI-1937] Rollback unfinished replace commit to allow updates while clustering

* No double locking and add a config to enable rollback
* Update config to be clear about rollback only on conflict
- Metadata table today has virtual keys disabled, thereby populating the metafields
for each record written out and increasing the overall storage space used. Hereby
adding virtual keys support for metadata table so that metafields are disabled
for metadata table records.
- Adding a custom KeyGenerator for Metadata table so as to not rely on the
default Base/SimpleKeyGenerators which currently look for record key
and partition field set in the table config.
- AbstractHoodieLogRecordReader's version of processing next data block and
createHoodieRecord() will be a generic version and making the derived class
HoodieMetadataMergedLogRecordReader take care of the special creation of
records from explictly passed in partition names.
* Enabling timeline server based markers
* Enabling timeline server based markers and marker based rollback
* Removing constraint that timeline server can be enabled only for hdfs
* Fixing tests
