> Project: Ambari
> Issue Type: Bug
> Components: stacks
> Affects Versions: 2.5.2
> Reporter: Alejandro Fernandez

> Priority: Blocker
> Labels: AMBARI-21348

> Repro Steps:
> * Installed BI 4.2.0 cluster on IBM Ambari 2.2.2 with Zookeeper
> * Upgraded Ambari to 2.5.2.0-146
> * Registered HDP 2.6.2.0 repo, installed packages
> * Ran service checks
> * Started Express Upgrade
> Result: _Service Check ZooKeeper_ step failed with {{KeeperErrorCode =
> ConnectionLoss for /zk_smoketest}}
> This was caused by Zookeeper dying immediately during restart:
> {noformat}
> Error occurred during initialization of VM
> Too small initial heap
> {noformat}
> {noformat:title=zookeeper-env.sh before upgrade}
