Smart rebalancing over date based indices

Elastic Stack Elasticsearch
1

ES 5.2

2 types of date based indices (e.g X-2018-10-10, y-2018-10-10)
20 shards per index.
30 indices from each index type (with 1 replica)
50 nodes.

Any suggestions how to spread all shards for best performance ?
For example, right now I have a few nodes with 5 shards from the same index.
Any idea how to avoid this behaviour ?

Best,
Idan

As you have less shards than nodes for each index, you may be able to use the index.routing.allocation.total_shards_per_node setting to get a more even distribution.
