[jira] [Commented] (SOLR-9251) Allow a tag role:!overseer in replica placement rules

["David Smiley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-9251?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15723258#comment-15723258 ] 

David Smiley commented on SOLR-9251:
------------------------------------

[~noble.paul] does the rule system allow one to have this rule but specify further that a particular shard may go on this overseer node (or any designated node for that matter)?  I hoped this would work:
{{&rule=shard:RT,role:overseer}}
{{&rule=shard:!RT,role:!overseer}}
This is a collection with the implicit router and thus named shards; one of them named "RT".  When I do this, Solr complains when attempting to create a replica that it could not identify nodes matching the rules.  Note that this notion isn't specific to the overseer... I have also tried with {{host:specifcHostName}} and got the same result.  I've tried various ways to try and achieve this but all in vain :-(

(apologies if you'd rather me ask on the user list)

> The reason to assign an overseer role to  a node is to ensure that the node is exclusively used as overseer. replica placement should support tag called {{role}}
> So if a collection is created with {{rule=role:!overseer}} no replica should be created in nodes designated as overseer
