You are running into: https://issues.apache.org/jira/browse/HIVE-1579
I've been meaning to submit a patch for this. I emailed the dev list
concerning a patch for it but got no reply...
Hive is crashing because it can't pull the debug logs for the failed
task, because it's trying to pull them from the url. If you change
taskid to attemptid in the url then you'll get the error logs you need
to debug the root cause.
I'll try and submit a patch at some point.
