Chesnay Schepler commented on FLINK-13417:
------------------------------------------
Making HA services pluggable is an orthogonal discussion to supporting multiple
ZK versions imo.
My current plan is to simple create 2 jars bundling ZK+ curator in
flink-shaded, have one in lib, one in opt, and users pick whichever they need.
This is pretty easy to set up (for us) and easy to understand (by users). It
also provides an nice stepping stone for creating self-contained ZK 3.4/3.5 HA
service implementations, since the dependencies are already there.
