Subject [jira] [Commented] (HDFS-11803) Add -v option for du command to show header line
Date Tue, 16 May 2017 20:24:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11803?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16013052#comment-16013052
] 

Chen Liang commented on HDFS-11803:
-----------------------------------

Thanks [~xiaobingo] for the work! v001 patch LGTM, just some NITs about the doc. Will it be
better to change "* The -v option displays..." to "* The -v option will display..."? such
that it will be consistent with the description of the other options. Also I was thinking
of keep the "The du returns three..." part but make the description of -v option simply say
that it will display the name of these field as a header line, rather than removing this part
and listing the name of fields only in -v option as in the patch.

> Like hdfs -count command, it's better to add -v for du command to show header line.
> Without -v,
> $ hdfs -du -h -s /tmp/parent
> {noformat}
> 1 G  1 G  /tmp/parent
> {noformat}
> With -v,
> $ hdfs -du -h -s -v /tmp/parent
> {noformat}

> 1 G   1 G        /tmp/parent
