Subject [jira] [Commented] (HDFS-13326) RBF: Improve the interfaces to modify and view mount tables
Date Tue, 17 Apr 2018 16:16:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-13326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16441094#comment-16441094

Íñigo Goiri commented on HDFS-13326:
------------------------------------

In that case, I would prefer for splitting this JIRA in two:
* The part that doesn't break compatibility (adding the update part).
* The part that removes functionality from the add behavior.

In this way, new patches will be easier to maintain and we can keep 2.9 and so on up to date
in code.

> From DFSRouterAdmin cmd, currently the update logic is implemented inside add operation,
where it has some limitation (e.g. cannot update "readonly" or removing a destination).  Given
the RPC alreadys separate add and update operations, it would be better to do the same in
cmd level.
