Geoffrey Jacoby commented on PHOENIX-4000:
------------------------------------------
This may also make stepping through Phoenix tests in a debugger easier since ZK
will be less likely to timeout and crash the testing utility. +1
> Increase zookeeper session timeout in tests to prevent region server aborts

> In a local run I saw region server aborts happening because of zookeeper
