Cache local map reduce job errors for additional logging
--------------------------------------------------------
Key: HIVE-2866
URL: https://issues.apache.org/jira/browse/HIVE-2866
Project: Hive
Issue Type: Improvement
Components: Logging
Reporter: Kevin Wilfong
Assignee: Kevin Wilfong
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.
