本文讨论了在使用官方版Hadoop 1.0.1与Cloudera Hadoop 2.0版本时，由于Counter从class改为了interface导致的IncompatibleClassChangeError问题。解决方法涉及替换到Hadoop 2.0版本的jar包。
开发环境中，使用的是官方版的hadoop 1.0.1版，而集群上的hadoop则是cloudera的hadoop 2.0版，之前兼容性还不错，直到使用了Counter。

报错如下：
FATAL org.apache.hadoop.mapred.Child: Error running child : java.lang.IncompatibleClassChangeError: Found interface org.apache.hadoop.mapreduce.Counter, but class was expected


其实从2.0开始，org.apache.hadoop.mapreduce.Counter从1.0版本的class改为interface。网上搜索时，看到也有不少人遇到类似问题，解决办法应该都是一样的，就是替换成2.0版本的jar就行，包括common、hdfs、mapreduce文件夹下的相应包。

相比Java的MapReduce api，Pig为大型数据集的处理提供了更高层次的抽象，与MapReduce相比，Pig提供了更丰富的数据结构，一般都是多值和嵌套的数据结构。Pig还提供了一套更强大的数据变换操作，包括在MapReduce中被忽视的连接Join操作。 pig 也是hadoop中的一员，是为了简化原生的mapreduce，不用运行jar便可以做mapreduce，只需要输入几行...

java.lang.IncompatibleClassChangeError异常的问题解决

保持类文件的一致性，确保类加载器正确加载类定义，并合理使用字节码操作，是避免此类异常的关键。到此这篇关于java.lang.IncompatibleClassChangeError异常的问题解决的文章就介绍到这了,更多相关java.lang.IncompatibleClassChangeError异常内容请搜索脚本之家以前的文章或继续浏览下面的相关文章希望大家以后多多支持。类加载器机制问题：在使用自定义类加载器或多重类加载器环境中，可能会加载错误的类定义。通过检查类加载器，确保加载的是预期的类定义。

Hadoop处理大量的数据，如果期间的输出数据、中间数据能压缩存储，对系统的I/O性能会有提升。 参考了网上不少资料，发现综合考虑压缩、解压速度、是否支持split，目前lzo是最好的选择。lzo最初在google code上托管，但后来转移到github了，所以以github为准。地址为： [code="java"]https://github.com/kevinweil/hadoop-...
