Sqoop进口问题 - java.lang.IncompatibleClassChangeError：发现了类org.apache.hadoop.mapreduce.JobContext，但接口预期

我使用Sqoop 1.4.3与hadoop 1.2.4和hive 0.11.0Sqoop进口问题 - java.lang.IncompatibleClassChangeError：发现了类org.apache.hadoop.mapreduce.JobContext，但接口预期

当我试图做一个sqoop进口：它扔了IncompatibleClassChangeError.

任何建议，以修复此问题。所用

Sqoop CMD：

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

跟踪：

您正在遭受版本冲突，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大多不兼容，所以您应该确保下载与您的Hadoop发行版相匹配的Sqoop版本。

嘿Charles Menguy，非常感谢您的回复。我会放弃它。与此同时，您是否知道Hadoop和sqoop发行版的任何组合，以便我将使用它们开始。感谢和问候， Nagashree – user2450449
