----------------------------------------

This was tested on a cluster using running CDH4.x's hadoop2 flavor.

> In a recent support case, the hbck repair tool would eventually hang because we didn't
handle the case where merge info is old using hadoop2 fs.listStatus semantics (throw exn instead
of return null).  this is a trivial patch that handles the newer hadoop2 semantics.
