我正在尝试使用java运行一个简单的sqoop导入程序。
我的程序：

String driver="com.vertica.Driver";
    Configuration config = new Configuration(); 
    config.addResource(new Path("/../../../mapred-site.xml"));
    config.addResource(new Path("/../../../core-site.xml"));
    config.addResource(new Path("/../../../hdfs-site.xml"));

    SqoopOptions options = new SqoopOptions();
    options.setConnectString(connection_string);
    options.setDriverClassName(driver);

    options.setUsername(username);
    options.setPassword("xxxxxxxxxxxxx");
    options.setTargetDir(directory path);
    options.setFetchSize(0);
    options.setSqlQuery("SELECT 123456 as runid, " +
            "business_date " +
            "FROM database.table " +
            "WHERE business_date=\'20140922\' " +
            "AND instrument_id=1037894110378941 " +
            "AND $CONDITIONS");

    int ret = new ImportTool().run(options);
    System.out.println("Return Val: "+ret);

我有以下错误

我尝试过的可能的解决方案。
在我的hadoop-env.sh中，javahome的值是

JAVA_HOME=/usr/lib/jvm/java-1.7.0-oracle-1.7.0.65.x86_64

我知道这听起来很重复，但相信我，我已经尝试了所有的解决方案中描述的解决方案中提供了类似的问题
我尝试用下面的代码在~/.bashrc中更改java\u home

JAVA_HOME=/etc/alternatives/java

在我的节点中安装了最新的java，但仍然会抛出相同的错误。
同样的查询在bash中工作。
注意：我没有权限将hadoop-env.sh中的javau home更改为共享系统。
在java程序中覆盖javahome的可能方法？

[已解决]
无需更改java\u home（或）hadoop\u mapred\u home（或）sqoop\u home
如错误所示，它无法找到sqoop库。而我在程序中使用了sqoop1.4.4库。请注意，我没有使用任何构建工具（maven、sbt或任何东西），我使用的是普通的eclipse并向程序中添加external.jar。
导出.jar时，我使用的是eclipse标准方法（file->export->java->runnable.jar文件）
在启动配置中，我选择了合适的项目，在库处理中，我使用了选项“将所需库打包到生成的jar中”
当我选择“extract required libraries into generated jar”并执行.jar文件时，它成功地执行了。
