[jira] [Commented] (HADOOP-7713) dfs -count -q should label output
column
[ https://issues.apache.org/jira/browse/HADOOP-7713?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14127194#comment-14127194 ]
Daryn Sharp commented on HADOOP-7713:
-------------------------------------
I understand Allen's point but I'm not sure how many options we'll realistically add. Again, I'd selfishly like the option in 2.x w/o breaking monitoring scripts. :)
Maybe I'm missing something obvious, but why is this needed? {{STRING_FORMAT.replace('d', 's')}}
