[jira] [Updated] (HADOOP-7713) dfs -count -q should label output
column
[ https://issues.apache.org/jira/browse/HADOOP-7713?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jonathan Allen updated HADOOP-7713:
-----------------------------------
Attachment: HADOOP-7713.patch
Removed use of STRING_FORMAT.replace.
My thoughts on the default align with Daryn's, it would be nice to get this into the v2 branch (I can never remember what fields are returned by count and always have to have the help page open in another window).
