Linux编译hadoop-cdh4.2.1

配置 安装Maven, Ant, Findbugs, protobuf, cmake 参考:http://cn.soulmachine.me/blog/20140214/ 注意CDH4.2.1需要用protobuf2.4.1编译，否则hadoop-common那里报错 在apache-maven-3.0.5/conf/settings.xml 更改maven镜像 mirror idnexus-osc/id mirrorOfc

替换jar包

从src/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-app/target里面拿出mr-app.jar重命名为hadoop-mapreduce-client-app-2.0.0-cdh4.2.1-20140801.jar

cd /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce
# 上传jar包
chmod 755 hadoop-mapreduce-client-app-2.0.0-cdh4.2.1-20140801.jar
ln -snf hadoop-mapreduce-client-app-2.0.0-cdh4.2.1-20140801.jar hadoop-mapreduce-client-app.jar
mv hadoop-mapreduce-client-app-2.0.0-cdh4.2.1.jar /tmp
