Ranger stops Syncing HDFS Policies

Expert Contributor

Ranger HDFS stops syncing HDFS policies, and we don't have any log statement in NN logs, to point to an error, although I can't see HDFS NN on Ranger plugin audit trail.

Is there an Log settings which would enable Ranger related logs in NN ?

Do you see any errors/exceptions in ranger logs about failure to download policies (in /var/log/hadoop/hdfs/hadoop-hdfs-namenode*.log file)? Typically, the text or ERROR log message is 'failed to refresh policies. Will continue to use last known version of policies'.
