Yes , this is expected to fail.
But why would anyone create a core with explicit coreNodeName. I wanted that case to be eliminated.
The idea is to only create the coreNodeName at the Overseer

> the slice needs to be checked null .because when create a new core with both explicite shard and coreNodeName, the state.getSlice(collection, sliceName) may return a null.So it needs to be checked ,or there will be an NullpointException
