> -----------------------------------------------------
>
> Key: SOLR-5991
> URL: https://issues.apache.org/jira/browse/SOLR-5991
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.7.1
> Reporter: Rich Mayfield
>
> Common maintenance chores require restarting Solr instances.
> The process of a shutdown becomes a whole lot more reliable if we can proactively move any leadership roles off of the Solr instance we are going to shut down. The leadership election process then runs immediately.
> I am not sure what the semantics should be (either accomplishes the goal but one of these might be best):
> * A call to tell a core to give up leadership (thus the next replica is chosen)
> * A call to specify which core should become the leader
