> 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}
