The block of code labeled 'integration test' seems dangerous. It appears
to override the Hadoop configuration whenever there's a keytab. Since we're
touching this code, it seems like the right time to remove or to defend this
'test' code.

> The local keytab path in YarnTaskManagerRunner is incorrectly set to the
> ApplicationMaster's local keytab path. This causes jobs to fail because the
