Subject [jira] [Commented] (HDFS-10646) Federation admin tool
Date Tue, 08 Aug 2017 00:20:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10646?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16117608#comment-16117608
] 

Chris Douglas commented on HDFS-10646:
--------------------------------------

This looks like a good first cut of the admin tool. Just a few nits:
* These are vestigial? There are also some {{SetConfiguration}} PB messages, not sure if/how
these are used...
{noformat}
+    } else if ("-perfBenchmark".equalsIgnoreCase(cmd)) {
// [snip]
+    } else if ("-setConfiguration".equalsIgnoreCase(cmd)) {
{noformat}
* {{printMounts}} can be static
* Totally subjective, but the commands seem a little verbose. addMount/removeMount/listMounts
could be add/rm/list without losing much
