Hi, We have installed ElasticSearch on 10nodes. 1 master,2 master+data,7 data nodes But now 10.186.193.59(102) act as primary.How to make 10.186.193.58 (ddlplels101) as primary ddlplels101 should be primary master and ddlplels102/103 should be secondary master + data node and remaining 7 nodes should be data nodes. node.name: ddlplels101 node.master: true node.data: false node.name: ddlplels102 node.master: true node.data: true node.name: ddlplels103 node.master: true node.data: true ip heap.percent ram.percent cpu load\_1m load\_5m load\_15m node.role master name 10.186.193.64 1 63 0 0.03 0.06 0.06 di - ddlplels107 10.186.193.67 2 63 0 0.00 0.01 0.05 di - ddlplels110 10.186.193.65 2 63 0 0.01 0.02 0.05 di - ddlplels108 10.186.193.63 2 63 0 0.01 0.05 0.06 di - ddlplels106 10.186.193.58 6 98 0 0.00 0.03 0.05 mi - ddlplels101 10.186.193.61 2 62 0 0.00 0.01 0.05 di - ddlplels104 10.186.193.59 2 62 0 0.00 0.01 0.05 mdi \* ddlplels102 10.186.193.60 1 62 0 0.00 0.01 0.05 mdi - ddlplels103 10.186.193.62 2 63 0 0.00 0.01 0.05 di - ddlplels105 10.186.193.66 2 62 0 0.02 0.02 0.05 di - ddlplels109 ---

Elasticsearch doesn't have the concept of a "primary" master. All master-eligible nodes are equally capable and likely to become the master. They are all equivalent. Generally, people designate three nodes as master-eligible only, and do not allow them to host data. So you should make `ddlplels102` and `ddlplels103` master-only like `ddlplels10`. ---
