Arpit Agarwal commented on HDFS-9415:
-------------------------------------
Thanks for the updated patch [~xiaobingo].
# I think you can remove this sentence _A comma separated list of groups is not
allowed. e.g., "supergroup" is good, but "supergroup1,supergroup2" is
incorrect._ Just stating it should be a single group name is sufficient.
# _The format are_ should be the _The format is_.
# You can just convert the numbered list in the {{dfs.cluster.administrators}}
description to paragraphs. I am not sure the numbered lists will render well
when the XML is convered to HTML.
# I did not mention the wildcard option for {{dfs.cluster.administrators}} as
IMO it is best left undocumented. If you choose to include it as Daniel
suggests, see {{AccessControlList#buildACL}} for the precise behavior of the
wildcard.
