Subject Cluster group for cache server nodes
Date Fri, 30 Jan 2015 20:33:22 GMT
ClusterGroup provides forCache method that allows to get a group of nodes
with the provided cache. But it includes CLIENT_ONLY nodes which are not
needed in most cases (if you want to execute some computations with cached
data, you need only data nodes).

I suggest to add forDataNodes(String cacheName, @Nullable String...
cacheNames) method that will exclude client nodes.

Alternatively we can add a boolean flag to existing forCache method, like
this:

forCache(boolean includeClients, String cacheName, @Nullable String...
cacheNames)

Thoughts?
