Subject [jira] [Commented] (HADOOP-8944) Shell command fs -count should include human readable option
Date Wed, 13 Aug 2014 17:54:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8944?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14095801#comment-14095801

Daryn Sharp commented on HADOOP-8944:
-------------------------------------

Like the other count jira, this would be great to have in 2.x.  I know we have various SE
and customer monitoring scripts that depend on this command, so I'd rather not have the headers
by default so we don't have to hunt down everyone using the command.

I think the header field names in count's former help message are probably a better choice
than the new ones in this patch.  I don't mind the upper/lower case so much as fields that
contain spaces.  I often like to write utilities that split a header and use them as map keys.
 Spaces in the header fields thwarts that.

I'd suggest using a single letter for the header option (maybe v(erbose)) to be inline with
the other commands.  Otherwise it will thwart the "one of these days" feature of allowing
option bundling.  Multi-char options are better implemented as "--opt".

> The shell command fs -count report sizes in bytes.  The command should accept a -h option
to display the sizes in a human readable format, i.e. K, M, G, etc.
