Jerry He commented on HBASE-10926:
----------------------------------
One more missing piece I need to add is the security check.
Currently preFlush() check is done on the region server security observer.
It works well originally since the RPC user from client is checked on the
region server.
But now the master starts the procedure and the region server hosting the
regions initiates the flush. That means the principal is 'hbase'?
We need to add preFlush() hook on the procedure master to check CREATE, ADMIN
on the table before we start the procedure.
> Use global procedure to flush table memstore cache

>
> 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.
