[Mondrian] Member Cache flush

That’s surprising.  The change for 2366 (https://github.com/YuryBY/mondrian/commit/64f142362450aabb9791f98ce7d5bd3e24a62f80) flushes out the native set cache, but there was nothing changed about segment cache flushing.

What are you seeing that shows segments from other cubes getting flushed?

Subject: [Mondrian] Member Cache flush

I was trying out the fix made with issue http://jira.pentaho.com/browse/MONDRIAN-2366 and found myself with a new problem... For some reason when i execute the code in the issue to clear the member cache for a specific cube, all the segments from other cubes get removed.

this is the code:

RolapCube cube = schema.lookupCube(cubeName, false)
CacheControl cacheControl = con.getCacheControl(null)

cube.hierarchies.each{ RolapHierarchy hierarchy ->
     if(hierarchy.hasAll()) {
           cacheControl.flush(cacheControl.createMemberSet(hierarchy.getAllMember(), true))

Any idea why this happens?
