[jira] [Created] (IGNITE-3972) Continuous query events could be lost on backup node when primary leaves.

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

             Summary: Continuous query events could be lost on backup node when primary leaves.
                 Key: IGNITE-3972
                 URL: https://issues.apache.org/jira/browse/IGNITE-3972
             Project: Ignite
          Issue Type: Bug
          Components: cache
    Affects Versions: 1.7
            Reporter: Vladimir Ozerov
            Assignee: Andrew Mashenkov
             Fix For: 1.8


Consider the following scenario:
1) One node in topology;
2) PARTITIONED cache with 1 backup;
3) Continuous query is set on the cache;

If another node joins the cluster, it will handle some updates. If it leaves the topology, the first node must flush it's own events from backup queue thus ensuring that no events are lost.

But this doesn't happen because {{GridContinuousProcessor.addBackupNotification}} method perform lookup only on remote infos map, while handler is local and hence located in local infos map.
