             Summary: Add warning if stored node attributes differ from stored 
in metastorage
                 Key: IGNITE-15010
                 URL: https://issues.apache.org/jira/browse/IGNITE-15010
             Project: Ignite
          Issue Type: Improvement
            Reporter: Ilya Shishkov


We can run a cluster node with attributes, which differ from stored in a 
metastorage. Online nodes take attributes of offline ones from the metastorage. 
If we use ClusterNodeAttributeColocatedBackupFilter in cache configuration and 
corresponding attributes differ from stored in metastorage, this can lead to 
incorrect partitions eviction and data loss.

So, situation of different node attributes should be logged. Feature could be 
switchable via JVM option.
