Hi, Is shard/replica balancing between nodes done for all the indices on a cluster, meaning elasticsearch spreads the shards and replicas for several indices as it would for one index?

I have a follow up question: I'm considering the following scenario in our system. Say we have 4 nodes and 1 shard per node. Now I see that the size of shards is almost at maximum disk size so I add a new index and opens a new node (and stop indexing to old nodes), that new index is defined with 4 shards. Does elasticsearch allocates the 4 shards to the same new node because size wise it is better for them to be allocated to this node, or does it put 2 shards in the new node and 2 others to the other "old" nodes (so the size problem remains as the new shards grow)?
