[jira] [Commented] (IGNITE-2394) Cache loading from storage is called on client nodes

["Valentin Kulichenko (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-2394?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15102489#comment-15102489 ] 

Valentin Kulichenko commented on IGNITE-2394:
---------------------------------------------

Described solution will break data loading for local cache created on client (test attached). I think we should treat local cache as a special case and just invoke the {{CacheStore}} only locally, regardless of whether it's a server or client.

> If to call cache.loadCache(...) then the loading from a storage will happen on all the nodes including client nodes.
> However, client nodes must be filtered out.
> If to be more precise at least this place of the code has to be modified

>         throws IgniteCheckedException {
>         ClusterGroup nodes = ctx.kernalContext().grid().cluster().forCacheNodes(ctx.name());
> {noformat}
> where forDataNodes() has to be used instead of forCacheNodes().
> Also additional tests have to be added.
