I had a cluster of 3 nodes running perfectly with no issues (all services running).. I added 3 new nodes to my cluster following all on-screen instruction (Including restarting Ganglia in order to recognize the new 3 nodes) …now Ganglia is down in all of my 6 nodes and there is no way I can bring them back on! I tried turning them on through ambari , they were green just for few seconds and went back to orange(slaves) & Red (Master node) in seconds.. I also tried to force restarting Ganglia from each node by typing the following command : ” service gmond restart” although it says Ganglia service is restarted but it is not taking into effect…
Can someone please help me out here? I am out of ideas!
