Hello everyone
I am using CDH3 Beta 4 distribution on 11 node cluster machines.
I successfully installed Hadoop. However, Pig seems to be giving us some
trouble. I installed Pig according to the instructions here (for Red
Hat): https://docs.cloudera.com/display/DOC/Pig+Installation, and it
will install successfully.
However, when I start the grunt shell, i have got a error message
Unexpected internal error. Failed to create DataStorage". and in pig log
file
Error before Pig is launched

I installed Cloudera Hadoop version 0.20.2+737in on cluster
mode<https://docs.cloudera.com/display/DOC/CDH3+Deployment+on+a+Cluster>, so
Pig is compatible.
thanks
