IllegalArgumentException: /tmp/zookeeper/myid file is missing

Question

I am trying to configure Kafka on multiple instances of EC2 by following this gist , but I am getting following error:

I am running this command:

$ bin/zookeeper-server-start.sh config/zookeeper.properties &

1 13308

Error:

[2017-03-22 08:21:00,314] ERROR Invalid config, exiting abnormally (org.apache.zookeeper.server.quorum.QuorumPeerMain)

My zookeeper.conf is as shown below:

dataDir=/tmp/zookeeper
# the port at which the clients will connect
#clientPort=2181
clientPort=2080
# disable the per-ip limit on the number of connections since this is a non-production config
maxClientCnxns=0


server.1=ec2-<GLOBAL_IP_1>.amazonaws.com:2888:3888
server.2=ec2-<GLOBAL_IP_2>.amazonaws.com:2888:3888
#add here more servers if you want
initLimit=5
syncLimit=2
tickTime=2000

Answer 1

When the server starts up, it knows which server it is by looking for the file myid in the data directory.

Create a file named myid under the dataDir i.e., /tmp/zookeeper for every Zookeeper server.

The myid file should contain the corresponding server number, in ASCII (For ex: 1), as the only entry in it.

What should be the entry in my case ?? – Matchboard

For host ec2-<GLOBAL_IP_1>.amazonaws.com, it is 1 and for ec2-<GLOBAL_IP_2>.amazonaws.com it is 2. – Sewellyn
