> Duplicate bucket files can get written to table by runaway task

> Saw a table get a duplicate bucket file from a Hive query. It looks like the
> following happened:
> 1. Task attempt A_0 starts,but then stops making progress
> 2. The job was running with speculative execution on, and task attempt A_1 is
> started
> 3. Task attempt A_1 finishes execution and saves its output to the temp
> directory.
> 5. A task kill is sent to A_0, though this does appear to actually kill A_0
> 6. The job for the query finishes and Utilities.mvFileToFinalPath() calls
> Utilities.removeTempOrDuplicateFiles() to check for duplicate bucket files
> 7. A_0 (still running) finally finishes and saves its file to the temp
> directory. At this point we now have duplicate bucket files - oops!
> 8. Utilities.removeTempOrDuplicateFiles() moves the temp directory to the
> final location, where it is later moved to the partition directory.
