Symptoms

Starting the Event Server in Cloudera Manager (CM) on the Oracle Big Data Appliance (BDA) during a BDA upgrade when the CM version is updated may raise the errors below during Step 8 of the upgrade. The example here is from a BDA upgrade from V2.0.1 to V2.2.1 where CM is being upgraded from CM Version 4.1.2 to CM Version 4.6.3.  Errors may be seen at other times/upgrade steps as well.

Note: The Event Server is down in CM as see by navigating: Home > mgmt > Event Server

Errors look like:

1. Errors look like below in earlier BDA versions:

2.  Errors may also look like below in later BDA versions:
