Oracle Big Data Appliance (BDA) cluster has V2.3.1 installed with Kerberos enabled. Primary and secondary key distribution centers (KDC) reside on BDA nodes.

After Reboot of V2.3.1 Secure BDA Cluster, Zookeeper and other HDFS Service Status is BAD.

Zookeeper services are bad as they are exiting abnormally.

Noticed below error in Zookeeper logs
