[master@sh-hadoop-datanode-250-102.elenet.me hiveserver2]$ java -jar /home/master/jolokia-jvm-agent.jar --host 0.0.0.0 --port 7777 start 28297
Couldn't start agent for PID 28297
Possible reason could be that port '7777' is already occupied.
Please check the standard output of the target process for a detailed error message.
