Subject [jira] [Commented] (SOLR-3167) Allow running embedded zookeeper 1 for 1 dynamically with solr nodes
Date Mon, 27 Feb 2012 12:41:53 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13217171#comment-13217171

Jan Høydahl commented on SOLR-3167:
-----------------------------------

Cool.

Less configuration is better. Have you considered cluster auto-discover so a new node can
be bootsrapped with no ZK host/port info at all?

> Right now you have to decide which nodes run zookeeper up front - each node must know
the list of all the servers in the ensemble. Growing or shrinking the list of nodes requires
a rolling restart. https://issues.apache.org/jira/browse/ZOOKEEPER-1355 (Add zk.updateServerList(newServerList)
might be able to help us here. Perhaps the over seer could make a call to each replica when
the list changes and use the update server list call.
