Subject [jira] [Created] (SOLR-6091) Race condition in prioritizeOverseerNodes can trigger extra QUIT operations
Date Mon, 19 May 2014 15:19:39 GMT
Shalin Shekhar Mangar created SOLR-6091:
-------------------------------------------

             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.
