Sqoop导入问题-java.lang.CompatibileClassChangeError:找到类org.apache.hadoop.mapreduce.JobContext，但需要接口

我正在使用

sqoop1.4.3

和

hadoop1.2.4

以及

hive0.11.0

当我尝试执行sqoop导入时：它抛出了不兼容的ClassChangeError。

有什么建议可以解决这个问题吗

使用的Sqoop cmd：

sqoop import --connect jdbc:mysql://localhost:3306/employees \
    --username test --password test

跟踪：

有人能建议我们可以配置哪个版本的Sqoop来让它工作吗？

您遇到了版本冲突，很可能您正在Hadoop 2.0上运行Hadoop 1.0上编译的代码。这是因为Hadoop 1.0和2.0基本上是不兼容的，所以您应该确保下载与Hadoop发行版匹配的Sqoop版本

嘿，查尔斯·门盖，非常感谢您的回复。我要试一试。同时，您是否知道Hadoop和sqoop发行版的任何工作组合，以便我开始使用相同的发行版。谢谢和问候，Nagashree
