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

             Summary: ConnectionLoss during recovery can cause lost updates, leading to shard
inconsistency.
                 Key: SOLR-3812
                 URL: https://issues.apache.org/jira/browse/SOLR-3812
             Project: Solr
          Issue Type: Bug
            Reporter: Mark Miller
            Assignee: Mark Miller
             Fix For: 4.0, 5.0


When we lose our connection to ZooKeeper due to connectionloss (that does not lead to expiration),
we can drop updates when replaying buffered updates and think we have successfully recovered.

We need to detect this and fail recovery when it happens. We should also increase how long
we wait for re connection when an update comes and we have lost our connection to zk (up to
the session timeout).
