------------------------------------------
BTW, it has been discussed a few times - there's no need to add numerical
modifier to a patch file: JIRA takes care about this automatically.
> FSDirectory#unprotectedConcat calls setModificationTime on a file

> Assignee: Eli Collins
> Priority: Minor
> Fix For: 0.22.0

> The HDFSConcat test fails when asserts are enabled because
> FSDirectory#unprotectedConcat calls INode#setModificationTime on a file, this
> method asserts that the argument is a directory. It should use
> setModificationTimeForce since we know the target is a file, it's mod time
> should be set to now unconditionally since we know we're modifying it. The
> behavior should be equivalent.
