Hi,
I was experimenting with the
cluster.routing.allocation.awareness.attributes setting. I started with
one data node in the cluster, with allocation awareness attribute set to
value1. I expect that all the shards will be allocated to this node.
Instead, only primary shards are allocated to
Take a look at the example here
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-cluster.html#allocation-awareness
Basically a shard and it's replica will never be allocated to the same
instance, which is what you are seeing.

Hmm... I'm reading the same document and came to the opposite conclusion.
:( My understanding is that if all the nodes have the same attribute, then
_all_ shards will be deployed among them. As soon as a node with different
attribute arrives, that's when the replica will not be deployed to
If you only have one node the replicas will never be assigned.
