Subject [jira] Updated: (HADOOP-3121) dfs -lsr fail with "Could not get listing "
Date Fri, 07 Nov 2008 02:08:44 GMT

Raghu Angadi updated HADOOP-3121:
---------------------------------

    Attachment: HADOOP-3121.patch

I hope attached patch clarifies what I mean. It behaves same as before and does not add extra
line of output that is unecessary.

For e.g. compare 'bin/hadoop fs -ls  /other' :

- with the patch attached (*and* trunk) : {noformat}
ls: could not get get listing for '/other' : org.apache.hadoop.security.AccessControlException:
Permission denied: [...]
{noformat}


- with your patch : {noformat}
ls: could not get get listing for '/other' : org.apache.hadoop.security.AccessControlException:
Permission denied: [...]
ls: There were totaly 1 exception(s).
{noformat}

I don't think most command print extra lines like 'ls: There were totaly 1 exception(s)' 
at the end..'

> It's probably because  file  was deleted between  items = fs.listStatus( and ls(items[i]

> I think lsr should ignore this case and continue.
