Jean-Daniel Cryans resolved HBASE-3767.
---------------------------------------

      Resolution: Fixed
    Release Note: hbase.htable.threads.max now defaults to Integer.MAX_VALUE. Setting this below the number of region servers can result into RejectedExecutionException.
    Hadoop Flags: [Reviewed]

Committed to branch and trunk, thanks for the review Stack.

> When creating a new HTable we have to query ZK to learn about the number of region servers in the cluster. That is done for every single one of them, I think instead we should do it once per JVM and then reuse that number for all the others.
