Sqoop用java失敗

我創建的java程序使用下面的代碼Sqoop用java失敗

String cmd = "import --connect \"jdbc:mysql://ip:3306/test\" --username root --password root --table seekay --target-dir /seekay -m 1"; 
Sqoop.runTool(cmd.split(" "));

當我運行該程序從MySQL數據庫導入HDFS表執行sqoop-1.4.5，我得到異常

下方

我在classpath中添加了所有依賴jar文件。幫我解決這個問題。

謝謝

我有同樣的問題。在逐步調試後發現它是log4j依賴性問題。

我從springframework的排除log4j的環比SLF4J的解決方案：

<dependency> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-data-jpa</artifactId> 
    <exclusions> 
     <exclusion> 
      <groupId>org.slf4j</groupId> 
      <artifactId>log4j-over-slf4j</artifactId> 
     </exclusion> 
    </exclusions> 
</dependency>
