      Description

      Test attached. This used to work fine in 1.6.

      This seem to be related to this jira and PR:
      https://issues.apache.org/jira/browse/IGNITE-3413
      https://github.com/apache/ignite/commit/89d64e74b697054a88c3a91433aaaf4f7fdd0284

      Here's the scenario:

      • First node starts with special attribute and creates a cache with the node filter that allows to deploy it only on nodes with this attribute
      • Second node starts without the attribute is started. When creating a continuous query to query the cache created by the first node, a NullPointerException is thrown.

      At first glance, it seems that because the NodeFilter prevented the GridContinuousProcessor.registerHandler() to be called , the ConcurrentMap<Integer, PartitionRecovery> rcvs is not initialized properly and NullPointerException is thrown on this line:

      @NotNull private PartitionRecovery getOrCreatePartitionRecovery(GridKernalContext ctx, int partId) {
              PartitionRecovery rec = rcvs.get(partId);
