Zookeeper: It is probably not running

Question

I am trying to start zookeeper on a remote virtual machine. I use this for my project regularly and I do not have any problems while starting the zookeeper. But lately when

Answer 1

Most probably Zookeeper server exited. If we are running it on a Linux box, use the linux commands. Some of them:

ps -ef | grep -i zookeeper
jps

etc.

Also, try running it in foreground

zkServer.sh start-foreground

Answer 2

In my case the issue was some how ClientPort attribute's value was missed in one of the box so in console it was showing as invalid config path.With the help of command 'zkServer.sh start-foreground' investigated and found root cause.

Answer 3

In My case the issue was $PATH issue... You will get what was the issue by running zookeeper in foreground

zkServer.sh start-foreground

Answer 4

I encountered same problem,too. In my case problem is about zookeeper locations configuration is not same for each node so zookeeper can not provide Quorum and mentioned nodes can not be part of cluster.

Please be sure server definition for each node is same.

For example for all nodes, server definition must be same as below

server.0=ip0:2888:3888
server.1=ip1:2888:3888
server.2=ip2:2888:3888
server.3=ip3:2888:3888
server.4=ip4:2888:3888
