[jira] [Commented] (BIGTOP-3205) zookeeper servers didn't deploy in Clustered (Multi-Server) / ensemble mode

    [ https://issues.apache.org/jira/browse/BIGTOP-3205?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16814774#comment-16814774 ] 

Evans Ye commented on BIGTOP-3205:
----------------------------------

You probably need to set the config in bigtop-deploy/puppet/hieradata/bigtop/cluster.yaml:
{code}
...
 hadoop_zookeeper::server::myid: "0"
 hadoop_zookeeper::server::ensemble:
   - ["0", "%{hiera('bigtop::hadoop_head_node')}:2888:3888"]
...
{code}

>             Project: Bigtop
>          Issue Type: Bug
>          Components: deployment
>    Affects Versions: 1.3.0

>            Priority: Major

> When I use './provisioner/docker/docker-hadoop.sh -C sample.yaml -c 3' to deploy a multi-node bigtop cluster, and include 'zookeeper' in sample.yaml's components list, such as:
>  
> {code:java}
> components: [hdfs, yarn, mapreduce, zookeeper, kafka]{code}
>  
> By doing this, a zookeeper server will be launched on each of the container nodes, totally three of them.
> Expected result is these three zookeeper servers should be connected to each other and form a zookeeper ensemble.
> Ref: [https://zookeeper.apache.org/doc/r3.4.6/zookeeperAdmin.html]  Section: Clustered (Multi-Server) Setup.
> However, the actual result is they are all standalone. And Kafka-servers only uses the zookeeper server in head node (node 1). Zookeeper servers on node 2 and node 3 are wasted, nobody knows them.
> More information: have a check of '/etc/zookeeper/conf/zoo.cfg', they all points to a single server which is the node 1's. Eg.
>   server.0=bdd7eae82f27.bigtop.apache.org:2888:3888
> Expected I should see three server.<id> lines in conf/zoo.cfg for a three-node zookeeper cluster.
>  
> The same error exists when deploying Bigtop onto multiple physical machines using 'puppet apply' and hiera.
