LGTM, I think the change in Store should be reverted though.

This is a tricky change to make and I want to understand the full consequences first. If I follow the flow of the code correctly, this code is called when a master wants to allocate a replica and checks if there are nodes that have data for the replica. Making this change here means that the fetching for this node will be considered as failed and will trigger a reroute in AsyncShardFetch. The replica might however still be allocated in ReplicaShardAllocator to another node or later allocated on any node in BalancedShardsAllocator. I'm not sure if that's the change we want. Can you leave this code as is for now?
