                 Key: IGNITE-4448
                 URL: https://issues.apache.org/jira/browse/IGNITE-4448
             Project: Ignite
          Issue Type: Improvement
          Components: cache

             Fix For: 2,0


Currently on joining a topology only affinity class name and partition number are checked between configurations of local and remote nodes.

This is not enough in case of configured backup filter and possible extension with primary filter and can lead to disastrous situations due to node misconfiguration.

We should implement something like {{AffinityValidator}} having signature as follows:

{noformat}
boolean validate(Affinity affinity)
{noformat}

Maybe it'll be useful for other grid objects as well, like {{CacheStore}},{{NodeFilter}}, etc.
