One thing missing from the list is that you need to have myid files on each server that correspond to the servers id (specified in the conf file). http://hadoop.apache.org/zookeeper/docs/current/zookeeperAdmin.html#sc_zkMulitServerSetup You'd have a config on each system that looks something lik

Btw, the docs for a particular version of ZK are always included in the release (under docs toplevel directory). The docs on the apache site are always for the latest stable release (currently 3.2.1). That's why you saw the discrepancy. Patrick Something Something wrote: Switched to 3.2.1.

Sorry, ignore this. My bad. These messages disappeared when I started ZooKeeper on other two instances. I tested this by killing 1 or 2 processes at a time. These messages start popping up when a process gets killed - implying that these instances are indeed talking to each other. Thanks. On

I keep getting "Connection refused" on EC2. Seems like it's a security issue on Amazon's EC2 environment. I have tried specifying machine names in following 4 ways, but nothing seems to help: server.1=domU-12-31-38-01-B8-47.compute-1.internal:2888:3888 server.1=domU-12-31-38-01-B8-47:2888:3888 s

Nearly! 1+2 are correct, but you also need to start ZooKeeper on all three instances with bin/zkServer.sh start. Henry On Wed, Dec 9, 2009 at 11:00 AM, Something Something < mailinglist...@gmail.com> wrote: > Now that I have your attention..next question... :) > > Now I would like to start a Zoo

The 3.2.1 command line is a lot nicer (has an actual prompt, tab auto-completion, shows your connection status etc) - if you can upgrade to 3.2.1 which is a good deal more modern, I would recommend it. If I recall correctly, there was no prompt in 3.1.1... Henry On Wed, Dec 9, 2009 at 9:36 AM, So

Without -server made some progress, but don't see a command prompt. Shouldn't I see one? This is what I see: 2009-12-09 17:27:56,709 - INFO [main:zookee...@341] - Initiating client connection, host=127.0.0.1:2181 sessionTimeout=5000 watcher=org.apache.zookeeper.zookeepermain$mywatc...@32fb4f 2009
