-----------------------------------
Summary: SolrCloud: Add API to move leader off a Solr instance
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
