Question

我尝试在单节点Hadoop安装上安装配置单元。我正在运行Mint 16.我已经尝试安装Hive 0.12.0和0.13.0。我已将HIVE_HOME，HIVE_HOME / bin和HIVE_HOME / lib（以及没有lib）添加到我的路径中。每次我从终端运行配置单元时，我都会得到以下堆栈

我还试图从源代码编译配置单元，但maven在测试中失败了。还有其他人找到了解决方案吗？

编辑：我没有在VM中运行它。我在我的系统上构建了安装程序，因此我在google上看到了一些建议删除CDH等旧版旧库的内容。

运行Oracle Java 1.8

$ hadoop version
Hadoop 2.4.0
Subversion http://svn.apache.org/repos/asf/hadoop/common -r 1583262

This command was run using /opt/hadoop-2.4.0/share/hadoop/common/hadoop-common-2.4.0.jar

当我尝试编译配置单元时：

Answer 1

看起来我有几个问题。我必须使用maven 3.0.5构建。然后我不得不在构建过程中跳过测试。最后，我有决斗罐，不得不删除

/opt/hadoop-2.4.0/share/hadoop/mapreduce/hadoop-core-0.20.2-cdh3u1.jar
/opt/hadoop-2.4.0/share/hadoop/tools/lib/hadoop-core-0.20.2-cdh3u1.jar

Hive 0.12.0 IncompatibleClassChangeError
