> I test current code on a 5-node cluster using RS(3,2).  When a datanode is corrupt, client
succeeds to write a file smaller than a block group but fails to write a large one. {{TestDFSStripeOutputStreamWithFailure}}
only tests files smaller than a block group, this jira will add more test situations.
