This post would appear to apply to your situation:

Your issue is almost certainly in YARN or Tez rather than in Hive, but regardless, you are probably up against a memory configuration issue. My best guess is that you have some component in Tez or Hive set too large and the resultant components won't fit into your max YARN container size.

Setting hive.llap.io.threadpool.size = value of no of executor resolved the issue
