    Description

      SOLR-5476 depends on Overseer restart.The current strategy is to remove the zk node for leader election and wait for STATUS_UPDATE_DELAY +100 ms and start the new overseer.
      Though overseer ops are short running, it is not a 100% foolproof strategy because if an operation takes longer than the wait period there can be race condition.
