Jerry He commented on HBASE-10926:
----------------------------------

HI, [~yuzhihong@gmail.com]

The timeout for the taskPool is covered by the timer that dictates almost everything in the
procedure.
{code}
this.executionTimeoutTimer = new TimeoutExceptionInjector(monitor, timeout);
{code}

I will correct the other things you mentioned.

> Currently, user can trigger table flush through hbase shell or HBaseAdmin API.  To flush
the table cache, each region server hosting the regions is contacted and flushed sequentially,
which is less efficient.
> In HBase snapshot global procedure is used to coordinate and flush the regions in a distributed
way.
> Let's provide a distributed table flush for general use.
