------------------------------------
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.
