Ranger UI is not accessible with Context initialization failed java.lang.NoClassDefFoundError:

I'm using hdp 25. and have installed ranger. All the services are running but ranger web service is failing. In the logs i could see below exception. Not sure on what is the issue. I have not enable ssl or kerberos on the cluster but have to enable then eventually.

Can you verify if commons-io-2.4.jar is in classpath?

If that jar is in classpath and this error persists, see copying that jar to /usr/hdp/<version>/ranger-admin/ews/lib/ resolves the issue.

this worked after removing javax.servlet-api-3.1.0.jar tomcat-el-api-7.0.68.jar servlet-api-2.5.jar and ranger-plugins-audit-0.6.0.2.5.3.0-37.jar from /usr/hdp/2.5.3.0-37/ranger-admin/ews/lib/
