Surendra Singh Lilhore commented on HDFS-11695:
-----------------------------------------------
Thanks [~umamaheswararao] for review..
bq. Also there is no logSync. We should have a logSync here. LogSync can be
outside fsdLock but inside fsnamesystem lock.
I think LogSync should be outside of both the lock. can you method
FSNameSystem#setStoragePolicy() ?
bq. SPS#postBlockStorageMovementCleanup, we should do logSync as well right.
Yes we should do logsync here also.
bq. Also as you said, we should not throw exception out may be valid case as I
explained one scenario in my previous comment. DO you want to handle that as
well? To do that, we should just make API as idempotent instead of AtMostOnce.
yes, I will handle this in next patch..
