问题描述

我有一个 Pig 脚本，它返回一个常量字符串值.当我尝试使用以下命令运行脚本时，出现 Pig ERROR 2998:

I have a Pig script that returns a constant string value. When I try to run the script with the following command, I get a Pig ERROR 2998:

pig -Dpig.additional.jars=Static.jar -f script.pig -l /dev/null -x local

script.pig

loaded = LOAD 'data/' USING com.twitter.elephantbird.pig.store.LzoPigStorage() AS (request);

script.pig

loaded = LOAD 'data/' USING com.twitter.elephantbird.pig.store.LzoPigStorage() AS (request);

加载 = 样本加载 0.00001;

loaded = SAMPLE loaded 0.00001;

size = FOREACH 加载 GENERATE Static(request);

sized = FOREACH loaded GENERATE Static(request);

转储大小;

导致错误的原因是什么?

What's causing the error?

推荐答案

这似乎是一个没有人发现的 java.lang.NoClassDefFoundError 错误.错误本身发生是因为 jvm 找不到您请求的类.

It appears to be a java.lang.NoClassDefFoundError error that nobody is catching. The error itself occurs because the jvm cannot find the class you requested.

具体来说，您似乎缺少 jar 中所需的目录结构.com.company.Static(即 Static.class 文件)应位于 jar 中的 com/company 目录下.查看其他SO问题了解更多详情.

Specifically, you seem to be missing the required directory structure in the jar. com.company.Static (i.e., the Static.class file) should be located under the com/company directory in the jar. See this other SO question for more details.

要快速修复，请查看 How 上的这个问题创建一个具有包结构的jar文件.

For a quick fix, take a look at this question on How to create a jar file with package structure.
