本地编译Hadoop小记
24 September 2012
##Git源码 git clone git://git.apache.org/hadoop-common.git 视网速不通，略慢
编译
cd hadoop-common
mvn install -DskipTests
抛异常：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.6:run (compile-proto) on project hadoop-common: An Ant BuildException has occured: exec returned: 127 -> [Help 1]

原因是缺少protocol buffer， 找不到protoc命令。 ###安装protocol buffer wget https://protobuf.googlecode.com/files/protobuf-2.4.1.tar.bz2 tar -xvf protobuf-2.4.1.tar.bz2 cd protobuf-2.4.1 ./configure && make make install
###导入Eclipse
mvn eclipse:eclipse -DdownloadSources=true -DdownloadJavadocs=true
