Resolution: Duplicate
> On a new cluster setup, new nodes never move out of the 'down' state.
> ---------------------------------------------------------------------
>
> Key: SOLR-6995
> URL: https://issues.apache.org/jira/browse/SOLR-6995
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.10.3
> Reporter: Darren Spehr
>
> This is related to a question I posted on
> [stackoverflow|http://stackoverflow.com/questions/28004832/solr-4-10-3-is-not-proceeding-to-leader-election-on-new-cluster-startup-hangs]
> a day ago.
> When deploying a new cluster, new nodes never proceed to an 'active' state. I
> have used both a custom (yet simple) deployment, as well as using the example
> framework you get when downloading the Solr distribution. Further inspection
> of the logs, and comparing them to the output of a 4.10.1 start up, it looks
> like the nodes never move on to leader election.
> For an apples-to-apples comparison I moved the solr/collection1 directory to
> solr/ttPoiMDS, and modified the core.properties appropriately. I also removed
> the 'conf' directory, assuming that it would pick this up from our ZooKeeper
> cluster.
> Here is the start up:
> {code}
> java
> -Dcollection.configName=ttPoiMDS
> -Djava.util.logging.config.file=etc/logging.properties
> -DzkHost=our_zk_host_1:<zk_port>
> -Djetty.port=8983
> -jar start.jar
