Subject Issue using hcatalog with MiniDFS and MiniMR
Date Mon, 12 Sep 2011 17:13:45 GMT
I am trying to test a MapReduce job that uses hcatalog and I have setup a MiniDFS and MiniMR
cluster that hcat can talk to.  When I run the MR job I get the error pasted below.  I was
wondering if anyone has seen this before and if hcat can work with a minicluster?

Thanks for your time reading this email.
