Jitendra Nath Pandey commented on HDFS-1197:
--------------------------------------------
Does HDFS-1779 partly fix this one? As per HDFS-1779, since bbw blocks are only
added to targets, the problem of premature completeFile should not happen due
to non-finalized blocks being added in addStoredBlock. That will leave only the
case of commitBlockSynchronization in HDFS-1197 which is a simpler fix. Is this
assessment correct?
