Subject [jira] [Commented] (HDFS-14226) RBF: Setting attributes should set on all subclusters' directories.
Date Sat, 09 Feb 2019 11:43:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-14226?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16764123#comment-16764123

Ayush Saxena commented on HDFS-14226:

[~elgoiri] As we were discussing in HDFS-14210 regarding the invocation.

I have extended a Unit Test to demonstrate the problem. Have put up the cases of file create
file, folder and direct on mount operation for the different Orders. This seems to solve the
problem which I was hitting. Pls give a check!!!

[~shubham.dewan] If you too have any extra case for verification which I might have missed
Pls let me know. I will check that too. :)
