             Summary: Flume HDFS Sink should retry close prior to performing a recoverLease
                 Key: FLUME-3223
                 URL: https://issues.apache.org/jira/browse/FLUME-3223
             Project: Flume
          Issue Type: Improvement
            Reporter: Miklos Csanady


Flume HDFS Sink will currently only attempt to close a file once, and if that fails, it will move to recoverLease. This appears to be causing some issues.

The recommendation is to modify the close behavior to retry the close a configurable number of times with a configurable interval in between before attempting the recoverLease.

There currently exists a {{closeTries}} and {{retryInterval}} property, however this only retries the rename operation, not the close operation as seen in the documentation:
{quote}The file may still remain open if the close call fails but the data will be intact and in this case, the file will be closed only after a Flume restart.
