es主分片迁移

1.查看当前的分片

[elasticsearch@localhost bin]$ curl -u elastic:elastic -X GET "192.168.1.134:19200/_cat/shards/metric_pl?v&h=shard,prirep,node,docs,store"
shard prirep node        docs   store

2.执行分片命令

curl -u elastic:elastic -X POST "192.168.1.134:19200/_cluster/reroute?pretty" -H 'Content-Type: application/json' -d'
{
    "commands" : [
        {
            "move" : {
                "index" : "metric_pl", "shard" : 3,
                "from_node" : "node-134", "to_node" : "node-14"
            }
        }
    ]
}
