Duo Zhang commented on HBASE-18906:
-----------------------------------
I have uploaded a patch in HBASE-18989 where I added more methods in
CompactionLifeCycleTracker for better tracking the completion of a compaction
request. I think we can do the same for flush.
Use a tracker instead of returning a CompletableFuture is that, we will also
pass the tracker to the CP hooks so you can carry some information on the track
and pass them to the hooks.
Thanks.

> While reviewing HBASE-18183, Andy pointed out that Phoenix uses
> waitForFlushesAndCompactions and/or waitForFlushes for diff reasons. This
> issue is to see why they need them and whether alternate ways are possible.
> This seems to be too much internal stuff and a normal CP hook calling these
> would be dangerous.
> If there are alternate ways for Phoenix not to use this and not landing in
> issues (As said by Andy) we should suggest/fix for them.
