Gour Saha commented on SLIDER-1166:
-----------------------------------
[~elserj] the synchronized init method will synchronize only against the other
synchronized close method for a specific instance of ZKIntegration. Since a
ZKIntegration object is created for every single destroy command it will not
synchronize against multiple ZKIntegration objects, all of which are now trying
to read/write to zkSessions. Hence the need for the synchronized block on
zkSessions.
> Every cluster stop operation creates and holds on to a zk session
