]

Elliott Clark updated HBASE-8299:
---------------------------------

    Attachment: HBASE-8299-2.patch

* Added in Max Compact size to Exploring compaction selection.
* Made sure that no RatioBasedCompactionPolicy can get stuck.  Turns out that in extreme cases
even the old compaction policy can get stuck.
* deleted the un-used policies (Smallest ratio)
* Tweaked the perf test so that it is more pluggable
* Added new use cases to the testing
* Changed the test output format.
* Added in comments with more details
* Fixed some style issues.
