> HIVE-5133 adds support for secure metastore access using delegation tokens.
> This is needed for example when a pig job is submitted via WebHcat, and the
> Pig script uses HCat, which has to access metadata and thus the metastore.
> When the job is complete the delegation token should be cancelled. HIVE-5133
> implements it as an OutputCommitter but this requires relevant jars to be
> shipped to the node where TempletonControllerJob is run. This makes
> configuration more difficult.
> Since Hive (and thus all the necessary jars for token cancellation) must be
> installed on the same node where WebHCat is running, the token can be
> cancelled from WebHCat when it receives a callback from Hadoop that the job
> is finished. Thus no additional jars need to be shipped anywhere.
