Íñigo Goiri commented on HDFS-13655:
------------------------------------
bq. the new branch is created only for this JIRA but not shared with other RBF
feature work( e.g. RBF security), right?
Correct, we would have one separate branch for this (we already have a separate
one for security).
Creating a branch is pretty easy, the only problem is that it adds overhead
when merging as it usually requires a vote, etc.
I'm OK with that.
The only caveat is that as [~brahmareddy] proposed in HDFS-13790, we would
commit that one to trunk as it's just refactoring.

> with [~elgoiri], there are some HDFS methods that does not take path as a
> parameter. We should support these to work with federation.
> The ones missing are:
> * Snapshots
> * Storage policies
> * Encryption zones
> * Cache pools
> One way to reasonably have them to work with federation is to 'list' each
> nameservice and concat the results. This can be done pretty much the same as
> {{refreshNodes()}} and it would be a matter of querying all the subclusters
> and aggregate the output (e.g., {{getDatanodeReport()}}.)
