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

             Summary: Lease renewal can hit a deadlock 
                 Key: HDFS-12754
                 URL: https://issues.apache.org/jira/browse/HDFS-12754
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.8.1
            Reporter: Kuhu Shukla
            Assignee: Kuhu Shukla
            Priority: Major


The Client and the renewer can hit a deadlock during close operation since closeFile() reaches
back to the DFSClient#removeFileBeingWritten. This is possible if the client class close when
the renewer is renewing a lease.
