> This happens during an ugprade from HDP 2.3.0 to 2.3.4.7. Couple nodes have
> Kafka broker/Zookeeper installed with no clients or any other components.
> Hence, during the installation, there is no HDFS package installed on this
> node. However, during the start up Ambari expects this node to have
> /usr/hdp/current/hadoop-client/conf' during the start up:
