Subject [jira] [Commented] (SOLR-9251) Allow a tag role:!overseer in replica placement rules
Date Tue, 06 Dec 2016 04:09:58 GMT


Noble Paul commented on SOLR-9251:

the rule {{rule=shard:RT,role:overseer}}  just does not look right. It means all replicas
 of shard {{RT}} must live in the node which is designated as overseer. why would you want
all replicas of a given shard live in one node? it must be conflicting with {{maxShardsperNode}}

Anyway, share your full create command

> 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
