> There are two issues.
> 1. Oozie doesn't set  ZK session timeout. So, curator uses default session timeout which is 1 min. 
> If there is GC pause for more than 1 min, or frequent GC pause because of which curator can't send heartbeat, the connection will be dropped and Oozie will shutdown itself.
> 2. Oozie uses ExponentialBackoffRetry with initial wait = 1sec and max retries = 3.
> so Oozie will only retry 3 times, with duration 1sec, 2 sec and 4 sec. We need increase max retries count to at least 10.
