Vinayakumar B commented on HDFS-10652:
--------------------------------------
bq. I change the condition replicaInfo.getBytesAcked() <
replicaInfo.getBytesOnDisk() to make sure that not only the bytesAcked is
smaller than the butesOnDisk, but the latter has to be equal to or bigger than
the chunk end
Since each time flushed content is 5000 bytes which is way more than chunk,
bytesOnDisk would have entire last packet (~5000bytes) flushed to disk, when
that exception thrown.
Anyway, change is fine though. Making it clear.
bq. BTW, I still saw a little flakiness, probably one out of 10 times, I would
see that the test failed,
Can you post the log output whenever you see the failure? This could be due to
shutting down wrong datanode?
