-----------------------------------
Assignee: Semen Boikov (was: Alexey Goncharuk)
> Need properly handle system caches
> ----------------------------------
>
> Key: IGNITE-668
> URL: https://issues.apache.org/jira/browse/IGNITE-668
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Reporter: Semen Boikov
> Assignee: Semen Boikov
> Priority: Blocker
> Fix For: sprint-3
>
>
> Issue is found by QA, scenario:
> - start one node with configuration for igfs (includes igfs data and meta
> caches)
> - start second node without cache configuration, igfs data and meta caches
> start on this node
> - try to use igfs, get error on second node:
> {noformat}
> Caused by: class org.apache.ignite.IgniteCheckedException: Failed to enlist
> new cache to existing transaction (cache configurations are not compatible)
> [activeCaches=[], cacheName=dataCache, cacheSystem=false, txSystem=true]
> at
> org.apache.ignite.internal.processors.cache.transactions.IgniteTxLocalAdapter.addActiveCache(IgniteTxLocalAdapter.java:3079)

> {noformat}
> Added simple test reproducing issue IgsfStartCacheTest.
> When cache processor starts igfs caches specified in configuration then these
> caches are marked as 'system', but when caches are dynamically started on
> second node these caches do not have 'system' flag.
> For me looks like GridCacheProcessor adds igfs and hadoop caches to
> 'sysCaches' collection to distinguish public caches and caches which can not
> be obtained from public API (e.g. Ignite.cache(cacheName)). But in code I see
> that for 'system' caches events are not recorded and 'utility cache pool' is
> used. I think 'utility cache pool' should not be used for igfs and hadoop
> caches.
