Oozie server not starting in HDP 3.1.4

[#1]

I am facing issue with Oozie server after restarting HDP stack.
Oozie server service starts and stops after a minute or 2.
I tried to follow the solutions provided to similar issue but not helping.

Following is the output in oozie-error.log file.

If I edit oozie-site.xml & check path for following value  /etc/oozie/conf/oozie-site.xml/oozie.service.SparkConfigurationService.spark.configurations , it is = /usr/hdp/current/spark-client/conf

Actual path I see on my master server =  /usr/hdp/current/spark2-client/conf

If I try to edit and modify the path & restart the service, old value is getting replaced.
As we see in the list, soft links for spark are in black colour as they don't exist.

Amey.
