Inigo Goiri commented on HDFS-10467:
------------------------------------
After checking the code, I think there might a bunch of overlaps between this
work and YARN-2915. I'd like to explore what we could move into Hadoop commons
to manage a federated space. I would probably open a new JIRA for that.
In addition, given the feedback collected during the last few weeks, it seems
like the community is OK with going into this direction so I'd like to start
moving the review process forward.
To simplify the review, I propose to convert this JIRA into an umbrella and
split the current patch into smaller subtasks. For now, I would like to start
with:
# Minimum Router
# State Store interface
# ZooKeeper State Store implementation
We can add more tasks if people think is the way to do. Probably, it's a good
idea to create a new branch for this effort. Thoughts? Opinions?
