Konstantin Boudnik commented on HDFS-6469:
------------------------------------------
bq, One really needs a paxos library that can be plugged in rather than an
external server-based solution like ZK.
What's the concern about external ZK server? It seems to be working pretty good
considering by all the QJM comments. I am not sure how this 'paxos' conclusion
was made?
