where,

<JobTracker jmx url> is the Java Management Extensions url, http://<<JobTracker host name>>:<<JobTracker port>>/jmx 

qry is Hadoop by default

service contains the type of the group, for example, DataNode, ResourceManager, JobTracker, ResourceManager, TaskTracker and other available groups
