stack commented on HBASE-8638:
------------------------------
+1 on adding debug to figure an issue.
What is this about:
LOG.info("Compaction failed at original callstack: " + formatStackTrace(ex));
What not just:
LOG.info("Compaction....", ex);
Your formatStackTrace doesn't seem to add anything?
Do you intend the fixes in ExploringCompactionPolicy?
Good on you Sergey.

> We are seeing some strange patterns with current compaction policy in some
> contexts (with normal writes, no bulk load). It seems like some logging is
> needed to understand what is going on, similar to old default policy
