Uma Maheswara Rao G commented on HDFS-12310:
--------------------------------------------
When I had discussion with [~andrew.wong], he suggested to have at least a
status command like 'setrep -w'
Here is the proposal:
Add a subcommand to wait to finish the SPS work. ex: hdfs storagepolicies
-satisfyStoragePolicy -path <path> -w
Here -w will make this call to wait and check the progress of SPS work. This
call could be block for long time until the work finished. We will add a client
API to get the SatisfierStatus of SPS work. SatisfierStatus could contain the
status of Failed/Retried Items, status=IN_PROGRESS, NOT_AVAILABLE (if SPS work
finished and cleaned up all the information or no SPS calls made to that
directory/file ), SUCCESS ( once Work finished, we could cache the status for
certain amount of time (say 1min or 5mins?). After this period, status would be
turned to NOT_AVAILABLE).
In the command line: '-w' will make use of above API and wait at client side.
Any comments?
