> 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.
