Apache Pig：無法運行我自己的pig.jar和pig-withouthadoop.jar

Question

我有一個運行Hadoop 0.20.2和Pig 0.10的集群。 我有興趣在Pig的源代碼中添加一些日志，並在集群上運行我自己的Pig版本。

我做了什么：

1. 使用'ant'命令構建項目

2. 得到了pig.jar和pig-withouthadoop.jar

3. 將jar復制到集群namenode上的Pig主目錄

4. 找工作

然后我有以下std輸出：

什么地方出了錯？ 除了在namenode的安裝目錄中替換pig.jar和pig-withouthadoop.jar之外，我還應該做什么嗎？

救命...

Answer 1

我錯過的一點是：pig-withouthadoop.jar應該用特定的Hadoop版本編譯。 我按照以下方式編譯了jar，它工作正常：

% ant clean jar-withouthadoop -Dhadoopversion=23
