Íñigo Goiri commented on HDFS-12858:
------------------------------------
We internally don't use any of those features.
That being said, those are obviously valuable features to have.
I think all of those are pretty much the same as {{refreshNodes()}} and it
would be a matter of querying all the subclusters and aggregate the output
(e.g., {{getDatanodeReport()}}.
We can create a new umbrella for these features.
The ones missing are:
* Snapshots
* Storage policies
* Encryption zones
* Cache pools
We can start an umbrella with a branch for those with something like "Adding
missing ClientProtocol methods to RBF".
As I mention, I don't have the environment to test it for real so I cannot help
much with actual development but I'd be happy to review.
