大象鸟mvn包错误

Question

我在我的系统中安装了hadoop 2.2.我想用象鸟罐.运行"mvn package"时出现以下错误.

错误:

---

我在pom.xml中添加了以下代码,但仍然存在错误.

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-lang3</artifactId>
    <version>3.1</version>
</dependency>

我该如何解决这个错误？

系统配置

Thrift version 0.9.1

Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 19:21:28+0530)
Maven home: /usr/lib/mvn/apache-maven-3.0.5
Java version: 1.7.0_25, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-7-openjdk-amd64/jre
Default locale: en_IN, platform encoding: UTF-8
OS name: "linux", version: "3.5.0-43-generic", arch: "amd64", family: "unix"

Hadoop 2.2.0.2.0.6.0-76

Answer 1

通过从http://archive.apache.org/dist/thrift/0.7.0/thrift-0.7.0.tar.gz下载,将Thrift从0.9.1更改为0.7.0 .提取并进入解压缩的文件夹.然后输入以下命令:

• chmod + x ./configure
• ./配置
• 使
• sudo make install

通过键入thrift -version来检查thrift版本.这应该返回"Thrift version 0.7.0"

然后转到elephant-bird文件夹并输入"mvn -Dmaven.test.skip = true package"

注意:使用跳过测试,因为某些测试失败.跳过测试选项解决了这个问题.

编辑:当编译JsonLoader的加载语句时,猪正在抛出错误,因为找不到json-simple-1.1.1.jar.谷歌的jar,你可以轻松找到它.(由于声誉低于10,无法发布链接)

关于hadoop-compat,在启动猪工作时抛出了一个错误.下载http://repo1.maven.org/maven2/com/twitter/elephantbird/elephant-bird-hadoop-compat/4.4/elephant-bird-hadoop-compat-4.4.jar (也见于<elephant-bird-folder -path> /hadoop-compat/target/elephant-bird-hadoop-compat-4.4-SNAPSHOT.jar

)

注册4个Jars在Pig中使用Elephant-Bird插件.
