intellij的maven工程"Server IPC version 9 cannot communicate with client version"錯誤的解決辦法

這個問題是java初始化hdfs client時出現的，原因是maven依賴的版本和hdfs的版本不一致。

mvn的hadoop-core最高只有1.2.1版本， 不能加這個配置， 使用hadoop-common + hadoop-hdfs + hadoop-client的2.7.1版本即可

注意，需要把intellij項目中External libraries裏面的hadoop-core.1.2.1.jar給手動刪掉，重新編譯才能生效。

我的配置：
