Logstash can't connect ElasticSearch.Got response code '400' contacting Elasticsearch at URL 'http://127.0.0.1:9200/_license'

There is my envirmoment. ElasticSearch 7.8.0 ,Logstash 7.14.0 I tried transfer MySQL data to ElasticSearch.There is my pipline config.

input {
      stdin {
       }
      jdbc {
        jdbc_connection_string => "jdbc:mysql://127.0.0.1:3306/test?characterEncoding=UTF-8&useSSL=false&autoReconnect=true"
        jdbc_user => "username"
        jdbc_password => "password"
       jdbc_driver_library => "/etc/logstash/pipeline/mysql-connector-java-8.0.26.jar"

       jdbc_driver_class => "com.mysql.jdbc.Driver"
       jdbc_paging_enabled => "true"
       jdbc_page_size => "50000"
       codec => plain { charset => "UTF-8"}
     tracking_column => created_at
     record_last_run => true
     last_run_metadata_path => "/opt/logstash/lastrun/.logstash_jdbc_last_run"

      statement_filepath => "/etc/logstash/pipeline/jdbc.sql"

      clean_run => false

       schedule => "* * * * *"
       type => "std"
     }
 }


output {

    elasticsearch {

        hosts => "127.0.0.1:9200"

        index => "test"

        document_type => "testdb"


        document_id => "%{id}"
    }

    stdout {

        codec => json_lines

    }
}

When I start the logstash, It looks some error,I cannt sync data..

[2021-08-11T01:11:55,385][WARN ][logstash.outputs.elasticsearch][main] Restored connection to ES instance {:url=>"http://127.0.0.1:9200/"}

I start logstash with docker,in the docker environment,it connect elasticsearch in shell(curl 127.0.0.1:9200) correctly.

Why does Logstash visit http://127.0.0.1:9200/_license?

  1. Logstash Version Should be Same as ElasticSearch Version.Thanks for @leandrojmp and @Val.
  2. The offical docker container has default setting,it contain xpack config,so I should editlogstash.yaml,remove xpack config or change it as note.

Some other advise.

With the license change from elastic, versions after 7.10 are not open source anymore and will only work with Elastic distribution of Elasticsearch using the Elastic License (the free one or one of the paid tiers).
