Kai Zheng commented on YARN-6840:
---------------------------------
Sharing some codes in Hadoop common sounds good. Or further, not sure if it's
good to have a generic Hadoop StatesStore (ZK maybe as the default back end)
across both HDFS and YARN. As I don't think there is very heavy usage of the
store (so can't share) so I guess the same store could be used to simplify the
deployment. We might evolve towards that.
