需求：Es版本數據升級:1.4.1-2.4.1
1.4.1 版本數據200W條數據；
[root@dmp9 wangzhanpeng]# curl dmp9:9201/_cat/indices?v

1、禁止節點分配；
curl -X PUT "dmp9:9201/_cluster/settings" -H 'Content-Type: application/json' -d'
{
"persistent": {
"cluster.routing.allocation.enable": "none"
}
}';
//確認成功；
{"acknowledged":true,"persistent":{"cluster":{"routing":{"allocation":{"enable":"none"}}}},"transient":{}}
2、執行同步刷新；
執行停止索引和執行同步刷新請求操作使分片恢復更加快速；
curl -XPOST 'http://dmp9:9201/_flush'
//結果
{"_shards":{"total":10,"successful":10,"failed":0}}
3、升級ES，並檢查集羣狀態；等到集羣變爲yellow；執行第四部；
curl -X GET "dmp9:9201/_cat/health"
[root@dmp9 logs]# curl -X GET "dmp9:9201/_cat/health?v"

4、啓動分配
curl -X PUT "dmp9:9201/_cluster/settings" -H 'Content-Type: application/json' -d'
{
"persistent": {
"cluster.routing.allocation.enable": "all"
}
}';
//啓動成功；
[root@dmp9 logs]# curl -X PUT "dmp9:9201/_cluster/settings" -H 'Content-Type: application/json' -d'
> {
> "persistent": {
> "cluster.routing.allocation.enable": "all"
> }
> }';
{"acknowledged":true,"persistent":{"cluster":{"routing":{"allocation":{"enable":"all"}}}},"transient":{}}
5、查看集羣恢復狀態
curl -X GET "dmp9:9201/_cat/health"
[root@dmp9 logs]# curl -X GET "dmp9:9201/_cat/health"
