> Using the CachingPrintStream we are storing errors that occur locally in
> Hive, but because local map reduce jobs are run in a separate JVM we are not
> storing that occur for these. We can use this same construct to store errors
> written to the subprocesses error stream. This way, when we log failed
> queries, these will give us a decent idea of why those queries failed.
