Anoop Sam John commented on HBASE-18906:
----------------------------------------

What I asked is if u know any history of adding this hack (like jira or discussion) pls share.
 That is to know the detail.. By looking at code, its not that much getting.   We are trying
to have a discussion and so knowing the details.

> 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.
