Hi, I believe I may have ran into this issue: https://issues.apache.org/jira/browse/RANGER-149
I am seeing the following error logs in my xa_portal.log: 2016-05-20 15:51:00,314 [timed-executor-pool-0] INFO org.apache.ranger.plugin.client.BaseClient (BaseClient.java:100) - Init Login: using username/password 2016-05-20 15:51:00,448 [timed-executor-pool-0] ERROR apache.ranger.services.hdfs.client.HdfsResourceMgr (HdfsResourceMgr.java:48) - <== HdfsResourceMgr.testConnection Error: org.apache.ranger.plugin.client.HadoopException: listFilesInternal: Unable to get listing of files for directory /null] from Hadoop environment [Dagobah_hadoop]. 2016-05-20 15:51:00,449 [timed-executor-pool-0] ERROR org.apache.ranger.services.hdfs.RangerServiceHdfs (RangerServiceHdfs.java:59) - <== RangerServiceHdfs.validateConfig Error:org.apache.ranger.plugin.client.HadoopException: listFilesInternal: Unable to get listing of files for directory /null] from Hadoop environment [Dagobah_hadoop]. 2016-05-20 15:51:00,449 [timed-executor-pool-0] ERROR org.apache.ranger.biz.ServiceMgr$TimedCallable (ServiceMgr.java:434) - TimedCallable.call: Error:org.apache.ranger.plugin.client.HadoopException: listFilesInternal: Unable to get listing of files for directory /null] from Hadoop environment [Dagobah_hadoop]. 2016-05-20 15:51:00,449 [http-bio-6080-exec-7] ERROR org.apache.ranger.biz.ServiceMgr (ServiceMgr.java:120) - ==> ServiceMgr.validateConfig Error:java.util.concurrent.ExecutionException: org.apache.ranger.plugin.client.HadoopException: listFilesInternal: Unable to get listing of files for directory /null] from Hadoop environment [Dagobah_hadoop]. Do I really need to format my Namenode in order to get the HDFS repo working? Won't that delete all of my files? Thanks.
