Hi Team, I tried to enable the HDFS Ranger plugin which asked me to restart NameNode/DataNode/Secondry Namenode but it failed to start with below error. NameNode works very well if I disable HDFS Ranger plugin. Appreciate your help to resolve this issue. I am using Ambari Version
2.5.0.3 and HDP Stack 2.5.3.0 Traceback (most recent call last):
