Eric Newton created ACCUMULO-959:
------------------------------------

             Summary: compactions starving METADATA table scans
                 Key: ACCUMULO-959
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-959
             Project: Accumulo
          Issue Type: Bug
          Components: tserver
         Environment: large cluster
            Reporter: Eric Newton
            Assignee: Keith Turner
             Fix For: 1.5.0


A large tablet had many files, and the compaction was taking a long time.  During this time,
it reserved so many readers that the scan of a metadata  tablet on the same host was starved
of readers, causing scans to back up.
