to create a hadoop cluster on aws.
I followed all the steps; I opened the required ports and managed to create a cluster with 3 medium instances on aws. But when the wizard attempts to start the cluster it fails.
Its stuck trying to start zookeeper1 and it is not providing a useful error. There is nothing in the logs. And the only error I can find is :
Command 'ZkStartPreservingDatastore' failed for service 'zookeeper1'
Anyone knows how to fix this and start the cluster?
Increase the maxClientCnxns to 500 in /etc/zookeeper/conf/zoo.cfg
The config path you mention here is invalid under a CM discussion. CM manages the configs itself, so all service-side config edits need to go to the UI (CM -> ZooKeeper -> Configuration -> (Find and Modify) -> Save Changes).

Can you provide either of the following information, after attempting the failure to start event again?
