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.
