Andrew Wang updated HDFS-11426:
-------------------------------
    Release Note: The `hdfs ec` CLI command has been substantially reworked to make the calling
patterns more similar to the `hdfs storagepolicies` command. See `hdfs ec -help` and the HDFS
erasure coding documentation for more information.

> 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.
