Karthik Kambatla updated HADOOP-9230:
-------------------------------------
Attachment: hadoop-9230.patch
I put more thought into this, but couldn't figure out the need for check
against legacy splits that is failing.
Could change the legacySplits implementation, but then the test doesn't really
make any sense.
Not finding an alternative, removed the check against legacy splits - uploading
the corresponding patch.
