Bikas Saha commented on HDFS-2902:
----------------------------------
While a NN is running the configured shared edit dir might fail and need to be
replaced. When a new location is available then the admin can update the config
and issue a refresh command to the NN. The NN will refresh the new edit dir and
start using it the next time it rolls the edit logs.
> Allow new edit logs dir to be configured while NN is running
