Marco Didonna commented on WHIRR-445:
-------------------------------------
I've never experienced this issued, not with version 0.6 not with version
0.7...so I guess it was something wrong with the version shipped by Cloudera.
I've also tested the latest trunk (five minutes ago) and it worked as expected.
IMHO you can close this issue.
