ES 分片爆满

ES报错：
Validation Failed: 1: this action would add [1] total shards, but this cluster currently has [2000]/[2000] maximum shards open;
[es01] unexpected error while indexing monitoring document

原因：ES集群默认有最大分片数2000的限制，达到最大数以后，无法添加新的分片，导致无法创建索引写入日志。

解决：在kibana上的DEV TOOL工具里执行如下命令。

PUT /_cluster/settings
{
  "transient": {
    "cluster": {
      "max_shards_per_node":12000
    }
  }
}
