Data loss when HDFS sink unable to close/rename file
Roshan Naik 2014-01-31, 21:21
What is the recommendation for this problem...

   When HDFS sink has trouble closing the tmp file on HDFS, the tmp file
lingers around without being closed or renamed. if HDFS sink is configured
to use compression, the data in this tmp file is not going to be
recoverable.

Does it make sense for Flume to actually keep retrying the close()
operation itself in case of failure ?
