I¹ve been developing for ZooKeeper for a couple months now, recently running
in a test configuration with 3 ZooKeeper servers. I¹m running 3.2.1 with no
problems. Recently I tried to move to a single server configuration for the
development team environment, but couldn¹t get the configuration to work. I
get the error java.lang.RuntimeException: My id 0 not in the peer list
This would seem to imply that the myid file is set to zero. But ...it¹s set
to 1.
What¹s puzzling to me is my original configuration of servers was this:
server.1=ind104.an.dev.fastclick.net:2182:2183 <--- The machine I¹m trying
to run standalone on.
server.2=build101.an.dev.fastclick.net:2182:2183
server.3=cmedia101.an.dev.fastclick.net:2182:2183
I just removed the last two lines, and ran zkServer.sh start. It fails with
the described log message. (Full log given below).
When I put the server.2 and server.3 lines back in, it works fine, and is
following the build101 machine.
I decided to try changing the server.1 to server.0, also changed the myid
file contents from 1 to zero. I get a very different error scenario: A
continuously-occurring Null Pointer exception:
2009-10-09 04:22:36,284 - WARN [QuorumPeer:/0.0.0.0:2181:quorump...@490] -

erElection.java:635)
at
org.apache.zookeeper.server.quorum.QuorumPeer.run(QuorumPeer.java:488)
I¹m at a loss to know where I¹ve gone astray.
Thanks in advance for any and all help.
