2 instances of zookeeper in the same machine.
Hi,
I'm trying to configure 2 instances of zookeeper in the same machine. My
zoo.cfg is
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/tmp/zookeeper
# the port at which the clients will connect
clientPort=2181
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=localhost:2888:3888
server.2=localhost:2889:3889
But I got this error:
2012-06-27 10:06:36,322 [myid:] - INFO [main:QuorumPeerConfig@101] -

How do I configure two instances of zookeeper in the same machine?

Hi,
you have to add a "myid" file in the dataDir that is defined in your
zoo.cfg.
(From zookeeper docu: "The myid file consists of a single line containing
only the text of that machine's id. So myid of server 1 would contain the
text "1" and nothing else. The id must be unique within the ensemble and
should have a value between 1 and 255.") This file is needed that the node
knows its own identity.
So you need to myid files (one for each zookeeper node).
And because you need too different myid files, you also need two different
zoo.cfg files. And set two different dataDirs in there.
Hope this helps,
Hartmut
