TestRawLocalContract create is failing until we do our own
BufferedOutputStream in passthrough of HADOOP-16830/ #2323 .
the HDFS checksum ones are about checksums not being found, which implies
they weren't being written. Which goes near output streams, doesn't it? Which
means there is a risk this is a genuine regression and not "hdfs tests being
flaky"
