Is es really load balance?

When i restart the nodes, i find all primary shards go to the node1, and
all replica shards go to the node0.
So, when i bulk write to the es, i find the node1 has more LOAD then the
node0.
I want to ask whether some thing i must set to avoid all shards go to one
node?

The follow is the monitor for the two node when i bulk write to es:

must set to avoid all shards go to one node?

Did you mean primary shards?

The difference between primary shards and replicas is very small (almost a
flag).

node1 has more LOAD then the node0

What do you by load?
If you are talking about OS load, you are probably doing the bulk request
to node1
and he is sending information to node0. So yes, node1 has more load than
node0.
If you make the bulk request to node0, you will see (I trully hope it) that
you get
the opposite LOAD.

Notice that it does not depend on the primary or replica thing.

Pablo

Yes, i mean primary shards. And i use 10 threads for bulk request to the es.There are 5 threads get connet to the node0, and another 5 threads connet to the node1.
So, i guess if the bulk write first going to the primary shards, and when there are enough data , then write to the replica shards(that means some times write to primary shard, one time write to replica shard)?
