Subject [jira] [Commented] (HADOOP-8691) FsShell can print "Found xxx items" unnecessarily often
Date Wed, 05 Mar 2014 21:54:52 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8691?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13921477#comment-13921477

Daryn Sharp commented on HADOOP-8691:
-------------------------------------

Just fyi, I posted an example patch I said wasn't tested.  I expected someone else to finish
the patch, not for it to be checked in as-is.

> The "Found xxx items" header that is printed with a file listing will often appear multiple
times in not-so-helpful ways in light of globbing.  For example:
> {noformat}
> $ hadoop fs -ls 'teradata/*'  
> Found 1 items
> -rw-r--r--   1 someuser somegroup          0 2012-08-06 16:55 teradata/_SUCCESS
> Found 1 items
> -rw-r--r--   1 someuser somegroup       5000 2012-08-06 16:55 teradata/part-m-00000
> Found 1 items
> -rw-r--r--   1 someuser somegroup       5000 2012-08-06 16:55 teradata/part-m-00001
> {noformat}
> Seems like it should just print "Found 3 items" once at the top, or maybe not even print
a header at all.
