when you say "remove the server from the ensemble", do you mean delete it? Like selecting the delete option? : https://dl.dropboxusercontent.com/u/133690147/Capture3.PNG ... View more

Hi   we have 4 zookeeper servers in the cluster. One of my hypotheses was stopping the zookeeper server on one of the 4 servers will solve the problem. Since that's not working, what else can we do? Should we try uninstalling zookeeper on one of the nodes?...If so, could you please tell me how to do that? I have been searching for a couple of days now for resources that would direct me to that direction. so far no luck.   if you need further info on our cluster, here's a screenshot for it: https://dl.dropboxusercontent.com/u/133690147/Capture.PNG   when i try to restart the w3 server (the server at the bottom of the picture above), I get the following error: https://dl.dropboxusercontent.com/u/133690147/Capture2.PNG   Thank you ...

Hi   We are using the zookeeper server on our google compute engine VMs. When we go to Cloudera manager, the status of Zookeeper says that "ZooKeeper service zookeeper must have an odd number of servers." Obviously we thought of shutting down one of the servers. Even when we stopper Zookeeper server on one of our nodes, the warning was still there. After this I have tried stopping, restarting and re-initializing the server but the warning message remains. Does anyone have any insight into this problem?   To make things worse, after I shut down the chosen node, I started getting this health warning message about that node.  Anyway, when I try restarting the zookeeper server on that machine, I get the following error message: " Command Details: Restart this ServerLast Refreshed: Oct 29, 2015 10:23:37 PM UTC Command Context Status Started at Ended at Restart this Server Server, hadp-inv-ibi-w3 Finished Oct 29, 2015 10:23:24 PM UTC Oct 29, 2015 10:23:36 PM UTC Command (2133) has failed Child Commands All   Failed Only   Active Only Command (Child commands) Context Status Started at Ended at Start this Server Server, hadp-inv-ibi-w3 Finished Oct 29, 2015 10:23:24 PM UTC Oct 29, 2015 10:23:36 PM UTC Supervisor returned FATAL.
