Summary: Expose SecurityEnabled boolean field in JMX for other services besides NameNode Key: HADOOP-14212 URL: https://issues.apache.org/jira/browse/HADOOP-14212 Project: Hadoop Common Issue Type: Improvement Reporter: Ray Burgemeestre Priority: Minor The following commit https://github.com/apache/hadoop/commit/dc17bda4b677e30c02c2a9a053895a43e41f7a12 introduced a "SecurityEnabled" field in the JMX output for the NameNode. I believe it would be nice to add this same change to the JMX output of other services: Secondary Namenode, ResourceManager, NodeManagers, DataNodes, etc. So that it can be queried whether Security is enabled in all JMX resources. The reason I am suggesting this feature / improvement is that I think it would provide a clean way to check whether your cluster is completely Kerberized or not. I don't think there is an easy/clean way to do this now, other than checking the logs, checking ports etc.? The file where the change was made is hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/NameNode.java has the following function now: {code:java} @Override // NameNodeStatusMXBean public boolean isSecurityEnabled() { return UserGroupInformation.isSecurityEnabled(); } {code} I would be happy to develop a patch if it seems useful by others as well? This is a snippet from the JMX output from the NameNode in case security is not enabled: {code} { "name" : "Hadoop:service=NameNode,name=NameNodeStatus", "modelerType" : "org.apache.hadoop.hdfs.server.namenode.NameNode", "NNRole" : "NameNode", "HostAndPort" : "node001.cm.cluster:8020", "SecurityEnabled" : false, "LastHATransitionTime" : 0, "State" : "standby" } {code} -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
