Ok, since the master doesn't contain any data, and don't do lot ofs IOs:
For 8GB RAM, what's the recommended HEAP_SIZE ? 7GB
and i don't fully understand the client (query management node).
Today, i have set node.master=true and node.data=true.
and with new master only, i will have masters only nodes and data only
nodes.
What the correct setting for client node ? node.client=true (with
node.master=false and node.data=false) with http adress set ?
so i don't need to tell the masters adress to the other applications like
logstash, tomcat, ... ?

these nodes as clients - ie query management.
You may need more RAM, but that should be a good start.

Hello,
I'm currently thinking of creating VM nodes for the masters.
Today, several nodes have master and data node roles.
But I have OOM memory errors and so masters crashed frequently.
What would be the correct hardware sizing for a master node only (like 2
CPUs, 4GB RAM) for managing a cluster of 20 data nodes with 4000 shards ?

if i set 4Gb heap for 8Gb system master node only, for what purposes are
the remaning 4GB ?
For the filesystem cache (but the master don't do IOs) ?

You should use 50% of your system memory for heap.
A client is just a node that is neither a master or a data node, though
once you set a node to master, you can leverage it as a client as well.
