问题描述

我的问题类似于这个未回答的问题:

[https://stackoverflow.com/questions/42140344/elephantbird-dependency-jars][1]

我已经注册了大象鸟运行所必需的所有罐子.

REGISTER '/MyJARS/elephant-bird-hadoop-compat-4.1注册'/MyJARS/json-simple-1.1.jar';REGISTER '/MyJARS/elephant-bird-pig-4.1.jar';注册'/MyJARS/elephant-bird-core-4.10.jar';注册'/MyJARS/google-collections-1.0.jar';

以下链接告诉我这些信息:1:从 HDFS 加载数据不适用于 Elephantbird

2:如何使用 pig 从 hdfs 加载 Twitter 数据?

我当前的版本:Hadoop:Hadoop 2.6.0-cdh5.7.3Pig:Apache Pig 版本 0.12.0-cdh5.7.3(重新导出)

我收到以下错误:

错误 1070:无法解析com.twitter.elephantbird.pig.load.JsonLoader 使用导入:[,java.lang., org.apache.pig.builtin., org.apache.pig.impl.builtin.]

感谢任何帮助，我尝试了几乎所有可能的网络解决方案.

解决方案

这是一个版本控制问题.在尝试了 this 链接中的许多 jar 之后，它终于与大象-鸟-猪-4.14.jar

REGISTER '/MyJARS/elephant-bird-hadoop-compat-4.1注册'/MyJARS/json-simple-1.1.jar';REGISTER '/MyJARS/elephant-bird-pig-4.14.jar';注册'/MyJARS/elephant-bird-core-4.10.jar';注册'/MyJARS/google-collections-1.0.jar';

My problem is similar to this unanswered question :

[https://stackoverflow.com/questions/42140344/elephantbird-dependency-jars][1]

i have registered all jars mandatory for elephantbird to function.

REGISTER '/MyJARS/elephant-bird-hadoop-compat-4.1
REGISTER '/MyJARS/json-simple-1.1.jar';
REGISTER '/MyJARS/elephant-bird-pig-4.1.jar';
REGISTER '/MyJARS/elephant-bird-core-4.10.jar';
REGISTER '/MyJARS/google-collections-1.0.jar';

following links tell me these info : 1 : Loading data from HDFS does not work with Elephantbird

2 : how to load twitter data from hdfs using pig?

My current versions :
Hadoop: Hadoop 2.6.0-cdh5.7.3
Pig: Apache Pig version 0.12.0-cdh5.7.3 (rexported) 

I receive following error :

ERROR 1070: Could not resolve com.twitter.elephantbird.pig.load.JsonLoader using imports: [, java.lang., org.apache.pig.builtin., org.apache.pig.impl.builtin.]

Any help is appreciated , I tried almost all possible solutions across web.

解决方案

This was an versioning problem. After trying many jars from this link , it finally worked with elephant-bird-pig-4.14.jar

REGISTER '/MyJARS/elephant-bird-hadoop-compat-4.1
REGISTER '/MyJARS/json-simple-1.1.jar';
REGISTER '/MyJARS/elephant-bird-pig-4.14.jar';
REGISTER '/MyJARS/elephant-bird-core-4.10.jar';
REGISTER '/MyJARS/google-collections-1.0.jar';
