-------------------------------------------
Summary: Race condition in prioritizeOverseerNodes can trigger
extra QUIT operations
Key: SOLR-6091
URL: https://issues.apache.org/jira/browse/SOLR-6091
Project: Solr
Issue Type: Bug
Components: SolrCloud
Affects Versions: 4.7, 4.8
Reporter: Shalin Shekhar Mangar
Assignee: Shalin Shekhar Mangar
Fix For: 4.9, 5.0
When using the overseer roles feature, there is a possibility of more than one
thread executing the prioritizeOverseerNodes method and extra QUIT commands
being inserted into the overseer queue.
At a minimum, the prioritizeOverseerNodes should be synchronized to avoid a
race condition.
