We have 3 nodes of elastic search all nodes is mater=true and data=true.
When we try to find the best practice almost is recommend to setup 1 node
for master=true,data=false and another 2 nodes is master=false,data=true.
So if we need to change it how going on with current master node. It will
be automatic allocation? or we have to delete and insert data again?
For another question Do you have any configuration suggestion detail is
bellow
