Hey All,

I'm in trouble.

I want perform rolling restart (so any service break) on our Elasticsearch Cluster (v 5.5).  
Particularity : One node contains four java instance of Elasticsearch.

It's ok this procedure :

1. Disable shard allocation.  
curl -X PUT "localhost:9200/\_cluster/settings?pretty" -H 'Content-Type: application/json' -d' {"transient": {"cluster.routing.allocation.enable": "none"}}'

2. Stop non-essential indexing and perform a synced flush (Optional)  
curl -X POST "localhost:9200/\_flush/synced?pretty"

3. Stop one node (so in my case, restart one node = restart four instances)  
Stop elasticsearch node

4. Start node (so my four instance going to start)

5. Reenable shard allocation.  
curl -X PUT "localhost:9200/\_cluster/settings?pretty" -H 'Content-Type: application/json' -d'  
{"transient": {"cluster.routing.allocation.enable": "all"}}'

6. Wait for the node to recover

7. Repeat on next node "multi instance"

So, it's better to stop/start master instance in first no ?

Also, i increase max byte recovery per seconde to speed up the rolling restart.
