Apache Pig:无法运行我自己的pig.jar和pig-withouthadoop.jar

Question

我有一个运行Hadoop 0.20.2和Pig 0.10的集群.我有兴趣在Pig的源代码中添加一些日志,并在集群上运行我自己的Pig版本.

我做了什么:

1. 使用'ant'命令构建项目

2. 得到了pig.jar和pig-withouthadoop.jar

3. 将jar复制到集群namenode上的Pig主目录

4. 找工作

然后我有以下标准输出:

什么地方出了错？除了在namenode的安装目录中替换pig.jar和pig-withouthadoop.jar之外,我还应该做什么吗？

救命...

Answer 1

我错过的一点是:pig-withouthadoop.jar应该用特定的Hadoop版本编译.我按照以下方式编译了jar,它工作正常:

% ant clean jar-withouthadoop -Dhadoopversion=23
