----------------------------------

             Summary: Remove race in OverseerTaskQueue#remove that can result in the Overseer causing a Zookeeper call spin spike.
                 Key: SOLR-13386
                 URL: https://issues.apache.org/jira/browse/SOLR-13386
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Mark Miller
            Assignee: Mark Miller
             Fix For: 7.7.2, 8.1


If the getData call hits NoNodeException, it will throw and the Overseer work queue processor will catch it and loop and repeat, which causes major zk exist call traffic or other such things.
