Mingliang Liu commented on HDFS-12374:
--------------------------------------
Lovely as the new format is, I think this JIRA major scope is invalid.
The reason is that, {{haadmin}} was not supposed to be HDFS specific while the
subclass {{DFSHAAdmin}} is. Option {{-ns}} is part of {{DFSHAAdmin}} instead of
{{haadmin}} command. The current documentation for {{DFSHAAdmin}} is correct
if you check the version from 2.7.
A few related JIRAs can be checked at [HDFS-8067], [HDFS-7324] and [HDFS-7808].
[~brahmareddy] and [~szetszwo] to chime in? Thanks,
