Kevin Minder commented on KNOX-180:
-----------------------------------
The first thing we need to figure out is that you appear to be out of disk
space on the host or VM that is running WebHCat. Given your reported success
with WebHDFS and Oozie I'd be surprised if this were the only issue. The other
thing that you should consider if you are not using a Sandbox VM for this
testing is changing the account being used to match a real user account in your
Hadoop cluster. This will involve changing the sample Groovy (i.e. username =
"mapred") and the default conf/users.ldif to include that account information.
