Noble Paul commented on SOLR-6517:
----------------------------------
bq.ecause I feel it's an unnecessary complexity that doesn't add enough value
to justify doing it now
Actually it is much simpler. If you look at the overseer roles implementation ,
you can figure it has not added any complexity

> Reporter: Erick Erickson

> Perhaps the final piece of SOLR-6491. Once the preferred leadership roles are
> assigned, there has to be a command "make it so Mr. Solr". This is something
> of a placeholder to collect ideas. One wouldn't want to flood the system with
> hundreds of re-assignments at once. Should this be synchronous or asnych?
> Should it make the best attempt but not worry about perfection? Should it???
> a collection=name parameter would be required and it would re-elect all the
> leaders that were on the 'wrong' node
> I'm thinking an optionally allowing one to specify a shard in the case where
> you wanted to make a very specific change. Note that there's no need to
> specify a particular replica, since there should be only a single
> preferredLeader per slice.
> This command would do nothing to any slice that did not have a replica with a
> preferredLeader role. Likewise it would do nothing if the slice in question
> already had the leader role assigned to the node with the preferredLeader
> role.
