--------------------------------------------

             Summary: In FileSystem.Cache, the closeAll methods should not synchronize on the Cache object
                 Key: HADOOP-12523
                 URL: https://issues.apache.org/jira/browse/HADOOP-12523
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs
            Reporter: Tsz Wo Nicholas Sze
            Assignee: Tsz Wo Nicholas Sze


All the closeAll methods holds the Cache lock so that when one of the three closeAll methods is being called, a new FileSystem object has to wait for the Cache lock.  The wait time can possible be long since closing a FileSystem can be slow.
