EC2でembulkを実行しても、通信出来ない旨のエラー文が出て実行時できません。

やりたいことはEC2内のローカルmysql DB dev2からdev3へDB内容をreplaceする処理になります。  
なので以下のようなconfigファイルを書いて実行しています。

```

    in:
      type: mysql
      host: xxx.xxx.xxx.xxx
      user: root
      password: "xxxxx"
      database: dev2
      socket_timeout: 0
      # 18.183.204.253
    
    out:
      type: mysql
      host: xxx.xxx.xxx.xxx
      user: root
      password: "xxxxx"
      database: dev3
      mode: replace
    
```

そして出ているエラーが以下になります。  
なにかアイデアをいただけましたらありがたいです。

```

question
java embulk
EC2でembulkを実行しても、通信出来ない旨のエラー文が出て実行時できません。
アクセスキーとシークレットキーを入力してないから動かないのではないですか？
