stack commented on HBASE-7847:
------------------------------
Thanks for digging. What happens if someone is running zk 3.3.x? I ask
because it is a little obnoxious expecting folks update their zk ensemble when
updating their hbase. At a minimum I'd think this sort of requirement would
make this a trunk only patch and even then, is it worth stipulating we require
at least 3.4 to run? On other hand, looking in requirements, we do not
require a particular version of zk. Could you poke to see if this feature
available and then selectively use the new code and fall back on the old if it
fails?
Thanks.
