Root Cause:
Mysql driver is not located in the class path for oozie server to use.
Solution: You need to copy mysql jdbc driver to required location.
[root@m2 oozie]# cp /usr/share/java/mysql-connector-java.jar /usr/hdp/2.3.4.0-3485/oozie/oozie-server/webapps/oozie/WEB-INF/lib/
Now restart your oozie server and it will be fine.
I hope it helped you to solve your issue, please feel free to give your valuable feedback or suggestion.
