Bug ID: 61100
Summary: Hive freezes starting a query, and produces the
following error...
Product: Analytics

"Ended Job = job_1387838787660_1390 with errors
Error during job, obtaining debugging information...
Job Tracking URL:

This happens to different types of queries, at different times, and doesn't
seem to bear any relation to the query itself; I reran the query that generated
the error /this/ time immediately after it errored out, and it worked fine.
