Andrew Wang commented on HDFS-12437:
------------------------------------
I've spent some time digging through this failure, and it's still related to
the same problem of the test setup being unable to write the partial blocks to
the expected lengths.
I think this is a test regression rather a product issue, so not a true blocker.
