Ivan Kelly commented on HDFS-4266:
----------------------------------
Looks good to me, but the test could be a little flakey as it seems to rely on
the fact that it will finish before the client socket read timeout triggers,
which would cause the client to try to replace the sleeping bookie, and then
fail because it can't build an ensemble. This behaviour is something we plan to
change (if you have ack quorum, the client shouldn't fail) but we haven't done
so yet.

> BOOKKEEPER-208 allows the ack and write quorums to be different sizes to
> allow writes to be unaffected by any bookie failure. BKJM should be able to
> take advantage of this.
