Bharath Mundlapudi commented on HDFS-1692:
------------------------------------------
Yes, I will be porting this one to trunk. We run our clusters in secured mode.
When a volume tolerated threshold is reached, shutdown is called but datanode
continue to run and doesn't exit. This change will address only in secured mode
and non secure mode shouldn't have this problem.
> In secure mode, Datanode process doesn't exit when disks fail.
