Gregory Chanan commented on HBASE-6775:
---------------------------------------
I'm not sure we will require ZK 3.4+ in 0.94.
Perhaps we could put this behind a Configuration parameter
(hbase.zookeeper.serverSupportsMulti or hbase.zookeeper.useMulti), which would
give the user the option of using multi if they know their cluster supports it.
I also contemplated trying to figure this out programmaticaly (calling "srvr"
via "send4LetterWord" on the zookeeper quorum), but I've been told this is a
bad idea. Trying to get more information on that approach.
> Use ZK.multi when available for HBASE-6710 0.92/0.94 compatibility fix

>
> HBASE-6710 fixed a 0.92/0.94 compatibility issue by writing two znodes in
> different formats.
> If a ZK failure occurs between the writing of the two znodes, strange
> behavior can result.
> This issue is a reminder to change these two ZK writes to use ZK.multi when
> we require ZK 3.4+.
