We didn't enable audit to solr or db,only audit to hdfs.The problem seems to be related to catalina.

Thank you very much for your reply. The problem we encountered was that ranger web ui of http://ranger-admin-host:6080/login.jsp could not be accessed. The error code returned was 404. It seems to have nothing to do with ranger audit.

After upgrade hdp from 2.4.2.0 to 2.6.1.0,ranger web ui become unavailble.The new ranger admin installed on other machines is accessible. Is it because of conflict with the previous version?Thanks in advance. ERROR in xa_portal.log: ERROR org.springframework.web.context.ContextLoader (ContextLoader.java:331) - Context initialization failed org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'loggingDataSource' defined in ServletContext resource [/META-INF/applicationContext.xml]: C ould not resolve placeholder 'ranger.jpa.audit.jdbc.url' in string value "${ranger.jpa.audit.jdbc.url}"; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'ranger.jpa.audit.jdbc.url' in string value "${ranger.jpa.audit.jdbc.url}"

There are ranger hbase-plugin with AD but no kerberos in our environment. We have found that authentication only works for OS users but not for AD users. Must hbase authentication enable kerberos? Doesn't hbase support AD authention?

Our cluster version is hdp-2.6.1, ambari-2.5.1. When the user executes the hadoop fs -mkdir command, an error occurs which is "create gc thread. out of system resources". We know that when the value of HADOOP_CLIENT_HEAP_SIZE is too small, the hadoop fs -ls command will appear OOM, but our cluster's HADOOP_CLIENT_HEAP_SIZE has been set to 8G, which we think is already a large enough value. We checked the user's ulimit, the maximum number of open files is 11000, and the maximum number of processes is 1024, but the number of processes at the time of the problem is unknown. Is the reason for the emergence of OOM not the two mentioned above? Is there any other possible reason?
