Prepare to compile the software

1. Download jdk1.7, maven3.2.1 and ant1.9.4 on the official website, decompress and set environment variables and then use them.

The environment variable is set as follows:

(1) execute vim / etc/profile

(2) add at the end of the document:

Export JAVA_HOME=/home/spark/jdk1.7 export MAVEN_HOME=/home/spark/apache-maven-3.2.1 export ANT_HOME=/home/spark/apache-ant-1.9.4 export PATH=$JAVA_HOME/bin:$MAVEN_HOME/bin:$ANT_HOME/bin:$PATH export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

(3) execute source / etc/profile

two。 After downloading and decompressing the protobuf2.5.0 on the official website, enter the directory and execute the following command:

. / configure make make check make install

3. Install other software, I use the yum command to install here.

Yum install cmake openssl-devel autoconf automake libtool (some software operating systems may be included, please use the rpm-qa command to check when installing) II. Download the Hadoop source code to start compilation

1. Log on to the official website: http://hadoop.apache.org/, find the download link and click in to download it.

two。 Decompress and compile:

Tar zxvf hadoop-2.4.0-src.tar.gz cd hadoop-2.4.0-src mvn package-Pdist,native-DskipTests-Dtar

BUILD SUCCESS appears more than half an hour later, that is, the compilation is successful, and the compiled files can be found in the hadoop-2.4.0-src/hadoop-dist/target folder.
