Noble Paul created SOLR-5476: -------------------------------- Summary: Roles per node Key: SOLR-5476 URL: https://issues.apache.org/jira/browse/SOLR-5476 Project: Solr Issue Type: Sub-task Reporter: Noble Paul
In a very large cluster the OverSeer is likely to be overloaded.If the same node is a serving a few other shards it can lead to OverSeer getting slowed down due to GC pauses , or simply too much of work . If the cluster is really large , it is possible to dedicate high end h/w for OverSeers It works as a new collection admin command command=assignRole&whitelist=overseer&blacklist=leader&blacklist=replica&node=node_name If a node is whitelisted for overseer it gets preference over others when overseer election takes place. If no whitelisted servers are available another random node will be picked up if the node is blacklisted for leade/replica , it won't be assigned any new shards -- This message was sent by Atlassian JIRA (v6.1#6144) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
