Subject [jira] [Created] (ACCUMULO-959) compactions starving METADATA table scans
Date Fri, 11 Jan 2013 19:00:15 GMT
Eric Newton created ACCUMULO-959:

             Summary: compactions starving METADATA table scans
                 Key: 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.
