Review comment:
This step fails on a multi node install since $METRON_HOME will not be
present on a non-Metron node. We need to add a step to create the directory
`$METRON_HOME/config/zookeeper` before updating the `metron_knox_installed`
flag file.
Attached is the from Ambari when restarting Metron Client on a non-Metron
node.
