             Summary: Seeing thread contention on FileManager
                 Key: ACCUMULO-4805
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4805
             Project: Accumulo
          Issue Type: Bug
            Reporter: Keith Turner
            Assignee: Keith Turner


Accumulo had a tablet server wide cache of open files.  Accessing this cache obtains a global
lock.  In profiling, I am seeing contention on this lock.
