> The replicationTest() cases in TestFileAppend4 currently assume that the file 
> has both valid replicas immediately after completing the file. However, the 
> datanodes may take some milliseconds to report the replica - we should only 
> expect 1 replica (fs.replication.min) immediately after close, and we should 
> allow up to a second or so before asserting that we reach replication 2.
