I am trying to start ZooKeeper on an EC2 instance. Here's what I did: 1) Downloaded & Unpacked ZooKeeper 3.1.1 on EC2 instance. 2) cp /conf/zoo_sample.cfg /conf/zoo.cfg 3) Changed the dataDir path to point to my EBS volume. 4) In one command window, ran /bin/zkServer.sh start (The last message I see is... "Snapshotting: 0)
5) Opened another command window, and ran jps (This shows a new process called, QuorumPeerMain. That's the only one I see.) 6) As per documentation, tried bin/zkCli.sh -server 127.0.0.1:2181 (This gives me IOException: USAGE) 7) So I ran: bin/zkCli.sh -server 127.0.0.1:2181 ls Got UnknownHostException: -server 8) So I tried various ways of specifying IP address in EC2, such as: 10.xx.xx.xx ec2-xx-xx-xx-xxx.compute-1.amazonaws.com domU-12-31-xx-xx-xx-xx.compute-1.internal domU-12-31-xx-xx-xx-xx None of them worked. Keep getting UnknownHostException. What am I doing wrong. Please help. Thanks.
