             Summary: Internal cache type inconsistency for IGFS caches
                 Key: IGNITE-2433
                 URL: https://issues.apache.org/jira/browse/IGNITE-2433
             Project: Ignite
          Issue Type: Bug
          Components: IGFS
            Reporter: Semen Boikov
            Assignee: Yakov Zhdanov


Each cache has intenal CacheType, it can be inconsistent on different nodes in this scenario:
- first node starts and ceates cache 'cache1'
- second node starts, it has igfs configured and 'cache1' is IGFS data cache
As result on first node 'cache1' is user cache, and on second node 'cache1' is internal cache (see cacheType related logic in GridCacheProcessor.start). This can cause errors, e.g. see check in 'IgniteTxStateImpl.addActiveCache' - if tx.system() is 'true' but 'cacheCtx.systemTx()' is 'false' then tx will fail.

The most simple fix is to check that locally started cache IGFS cache has the same internal type as cache with the same name started before and prevent start if this check fails.
