[jira] [Created] (HDFS-13655) Adding missing ClientProtocol methods
to RBF
Xiao Chen created HDFS-13655:
--------------------------------
Summary: Adding missing ClientProtocol methods to RBF
Key: HDFS-13655
URL: https://issues.apache.org/jira/browse/HDFS-13655
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Xiao Chen
As discussed 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()}}.)
