elasticsearch7 分片不足

1、场景说明：

[2020-06-17T12:01:18,241][WARN ][logstash.outputs.elasticsearch] Could not index event to Elasticsearch. {:status=>400, :action=>["index", {:_id=>nil, :_index=>"bizlog-wxxcx-2020.06.17", :_type=>"_doc", :_routing=>nil}, #<LogStash::Event:0x5b51884a>], :response=>{"index"=>{"_index"=>"bizlog-wxxcx-2020.06.17", "_type"=>"_doc", "_id"=>nil, "status"=>400, "error"=>{"type"=>"illegal_argument_exception", "reason"=>"Validation Failed: 1: this action would add [2] total shards, but this cluster currently has [5000]/[5000] maximum shards open;"}}}}

2、处理思路：

7版本以上的elasticsearch，默认只允许1000个分片，问题是因为集群分片数不足引起的。

3、处理步骤：

3.1、登录elasticsearch-head：

http://IP:端口/?auth_user=账号&auth_password=密码

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

3.2、具体配置如图所示：
