                 Key: HBASE-2405
                 URL: https://issues.apache.org/jira/browse/HBASE-2405
             Project: Hadoop HBase
          Issue Type: Bug
            Reporter: stack
             Fix For: 0.20.4, 0.21.0


JGray and Karthik observed yesterday that a regoin open message arrived at the regionserver but that the regionserver worker thread did not get around to the actually opening until 45 seconds later (region offline for 45 seconds).  We only run a single Worker thread in a regoinserver processing open, close, and splits.  In this case, a long running close (or two) held up the worker thread.  We need to run more than a single worker.  A pool of workers?  Should opens be prioritized?
