------------------------------------------
The current patch does fix the Pig but the MR job would fail to find missing
HCat classes in classpath, see HIVE-5188.
> webhcat jobs that need to access metastore fails in secure mode

>
> Webhcat job submission requests result in the pig/hive/mr job being run from
> a map task that it launches. In secure mode, for the pig/hive/mr job that is
> run to be authorized to perform actions on metastore, it has to have the
> delegation tokens from the hive metastore.
> In case of pig/MR job this is needed if hcatalog is being used in the
> script/job.
