> Flume HDFS Sink should retry close prior to performing a recoverLease

>                 URL: https://issues.apache.org/jira/browse/FLUME-3223
>             Project: Flume
>          Issue Type: Improvement

>            Assignee: Miklos Csanady
>            Priority: Major
> 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.
