Subject [jira] [Commented] (HDFS-14226) RBF: Setting attributes should set on all subclusters' directories.
Date Sat, 09 Feb 2019 17:43:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-14226?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16764191#comment-16764191
] 

Íñigo Goiri commented on HDFS-14226:
------------------------------------

Thanks [~ayushtkn], I think this is the right direction.
I would refactor the tests to create the folders and files to all the order types but check
them with different parameters.

I would also rename {{isPathAll()}} to {{isFolderAll()}} (I think this one was missing some
order).
Then to cover the whole semantic, I would also create {{isFileAll()}} which basically would
be only RANDOM.
