Anastasia Braginsky commented on HBASE-14921:
---------------------------------------------
All code review comments from review board were addressed. All replies are in
the review board. As I have said above the main concerns are:
1. Correctness exceptions -- this is under investigation and is going to be
fixed
2. The concern about how much the compaction-estimation costs -- we are going
to run the PE tool ourselves
3. The problem with small flushes to disk due to lack of compaction -- no doubt
this can be arranged, but probably not under this JIRA
This is my summary
