Review comment:
After thinking about it, we shouldn't have this check. Just because
`MROutputCommitter` delegates all the calls to an inner committer object
(implementation of this inner field is determined by
`mapred.output.committer.class`), it doesn't mean all Tez output committer
implementations should or will in the future.
