Validation Failed: 1: this action would add [1] total shards, but this cluster currently has [1000]

错误信息：

Validation Failed: 1: this action would add [1] total shards, but this cluster currently has [1000]

问题：

分片数量超过限制数1000

原因：

elasticsearch7版本及以上的，默认只允许1000个分片，因为集群分片数不足引起的。

解决：

在kibana的tools中改变临时设，如图：

解决：

PUT /_cluster/settings
{
  "transient": {
    "cluster": {
      "max_shards_per_node":10000
    }
  }
}
