Andrew Wang commented on HDFS-11426:
------------------------------------
Hi [~surendrasingh] so your review comment actually relates to HDFS-11428 which
I already have a patch up for. {{setECPolicy}} requires an ECPolicy object,
which we can't get without calling {{getECPolicies}} first. HDFS-11428 changes
it to take a string like {{setStoragePolicy}} which avoids this extra RPC.
I plan to commit this by EOD based on Wei-chiu's +1, hoping that we can address
further issues in follow-on JIRAs.

> The {{hdfs erasurecode}} CLI is similar to {{hdfs storagepolicies}} in terms
> of functionality, but different in terms of behavior. Let's refactor
> {{ECCli}} to be more similar to the various Admin classes we already have,
> and also make its calling syntax mimic {{hdfs storagepolicies}} as closely as
> possible.
