SOLR-3836 : When doing peer sync, we should only count sync attempts that cannot reach the given host as success when the candidate leader is syncing with the replicas - not when replicas are syncing to the leader. SOLR-3835 : In our leader election algorithm, if on connection loss we found we did not create our election node, we should retry, not throw an exception. SOLR-3834 : A new leader on cluster startup should also run the leader sync process in case there was a bad cluster shutdown. SOLR-3772 : On cluster startup, we should wait until we see all registered replicas before running the leader process - or if they all do not come up, N amount of time. SOLR-3756 : If we are elected the leader of a shard, but we fail to publish this for any reason, we should clean up and re trigger a leader election. SOLR-3812 : ConnectionLoss during recovery can cause lost updates, leading to shard inconsistency. SOLR-3813 : When a new leader syncs, we need to ask all shards to sync back, not just those that are active. SOLR-3807 : Currently during recovery we pause for a number of seconds after waiting for the leader to see a recovering state so that any previous updates will have finished before our commit on the leader - we don't need this wait for peersync. SOLR-3837 : When a leader is elected and asks replicas to sync back to him and that fails, we should ask those nodes to recovery asynchronously rather than synchronously.
