Hi I have a cluster of 3 systems each of 32GB RAM and 1 TB HD. I have clustered all the three and able to start and run Hadoop Successfully.
I have installed Hbase on the master node. Now am trying to start Zookeeper in the cluster. When I start zookeeper and give command ./zkServer.sh status its telling 'Zookeeper might not be running... '. When I start zookeeper on all Nodes, zookeper on Master node becomes follower and when an MR is run , It will run 90% on reducer part then throws error 'Not able to find the region server.'. When checked zookeeper logs, Am viewing 'Connection error'. There is proper ssh across all 3 systems. I have tried giving iptables -flush too, but no luck!! I have tried another option by allowing Hbase to handle its own zookeeper. HQuarampeer starts successfully, and I am able to process 3GB file through MR for first time. But from second run zookeeper on one of the nodes getting killed. not able to figure out the issue. Please help!!!
