I have a cluster of two nodes and have the following configs for shards and
replicas:
index.number\_of\_shards: 10
>
index.number\_of\_replicas: 1
But when I index around 10k data or just one data, I find that there are
always 4 replica shards not to be allocated.
Is there a method to allocate all replica shards on the two nodes? Thanks
in advance.

Try removing the replicas and then readding them.
You can also force allocation -

Because it's difficult to recognize which shards are replica (I haven't
installed the head plugin), I removed all of the index data, tried to
reindex the data but got the same results that there were still some
replica shards not to be allocated.
I want to know why there're some replica not to be allocated.
"shard allocation filter" seems troublesome. So is there another way to
solve this problem other than using shard allocation filter?

I add another node into the cluster and now after I index data, the state
of the cluster becomes green.
If the replica number is 1, must I have at least 3 nodes to assure that the
state of the cluster is green?

It's caused by different versions of ES. In my previous test, one node use
ES-1.1.1 and the other uses ES-1.1.2. After every node of the cluster uses
the same version of ES, then the first problem disappears.
Thank you very much!
