问题原因
```
[indices:admin/create]]; nested: IllegalArgumentException[Validation Failed: 1: this action would add [6] total shards, but this cluster currently has [2998]/[3000] maximum shards open;];
```
显示分片打开超过1000 的分片
Elasticsearch 7.x 默认 cluster.max_shards_per_node 为 1000

# 2.解决方法
通过API 进行修改 ,调整分片为每个节点的分片为10000
```
PUT /_cluster/settings
        {
          "persistent": {
            "cluster": {
              "max_shards_per_node":10000
            }
          }
        }
```
- transient 临时
- persistent 永久

启动后验证一下：
```
GET /_cluster/settings
```
