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