Ship it!
sorry I didn't look at this earlier.
Looks fine to me. Please see if the code needs to be rebased.

bq. Review request for Flume.

bq. Summary
bq. -------
bq.
bq. 1) All HDFS actions are now done in async mode
bq. 2) If an HDFS append timesout, the file is closed and reopened.
bq. 3) Batching is now handled by BucketWriter which was always aware of the batch size.

bq. Testing
bq. -------
bq.
bq. 1) Unit tests were added for close/reopen scenario.
bq. 2) All unit tests pass
bq. 3) I manually verified this patch improved FlumeNG's behavior when the datanode it's writing to is restarted. In the past FlumeNG had to be restarted, now Flume moves on and starts writing to a new file.
