Hi,
The HDFS writer is not doing that but the LocalWriter (HDFSMover) is exactly doing this.

Hello,

When collector is in middle of committing chunks to sequence file, if hdfs becomes unavailable,
the collector bails out. What happens to .chukwa file the collector is working on? This file
will not be renamed to .done file. The file as such would become orphan as next time collector
starts, it will not carry on with this file.

Is there any process, that looks for orphan files and takes action on them? (like rename to
.done)

Thanks,
Jaydeep
