             Summary: 3rd-party persistence: Backup and primary partitions data differ after a single IgniteCache.get that loaded data from the persistent store which breaks skipStore behavior
                 Key: IGNITE-11296
                 URL: https://issues.apache.org/jira/browse/IGNITE-11296
             Project: Ignite
          Issue Type: Bug
          Components: cache, cassandra
    Affects Versions: 2.7, 2.5
            Reporter: Igor Kamyshnikov


1) run 2 ignite servers on different machines
(this is important because of org.apache.ignite.internal.processors.cache.GridCacheContext#selectAffinityNodeBalanced - it takes into account MACs)

2) run cassandra and insert some records into cassandra

3) connect to the ignite cluster as Ignite client node and invoke
IgniteCache.get(pk);

4) execute IgniteCache.withSkipStore().get(pk) several times
The values returned will be randomly NULLs or non-NULLs.

5) depending on a chance, the data loaded in 3) can appear in primary partition or backup partition. If they are in backup partition, then they are not visible to Ignite JDBC.
