stack commented on HBASE-2467:
------------------------------

Todd updated hdfs-895 patch for 0.20 append.  I built an hadoop with his new patch.  Ryan
posted it up on his repo.  Going to test it basically works.

> HDFS-895 changes hflush() to be able to run concurrently from multiple threads, where
flushes can be concurrent with further writes to the same file.
> We need to rip out/amend the group commit code a bit to take advantage of this.
