    • hbase.htable.threads.max now defaults to Integer.MAX_VALUE. Setting this below the number of region servers can result into RejectedExecutionException.

    Description

      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.
