Hadoop 2.4 maven build OutOfMemoryError: Java heap space

Question

I was trying to build the complete source code of Hadoop on my mac. When I try building I constantly run into the error: "java.lang.OutOfMemoryError: Java heap space". I tried to set the maven opts using the command: export MAVEN_OPTS="-Xms256m -Xmx1024m" and export MAVEN_OPTS="-Xmx2g -XX:MaxPermSize=512M -XX:ReservedCodeCacheSize=512m". But none of these solutions have helped me. I have a 4GB DDR3 RAM. 2.3 GHz intel core i5 processor. Please provide me the right direction. Logs:

Answer 1

For mac/linux users, just add an export statement to your ~/.profile (or similar file name). For example:

export MAVEN_OPTS="-Xmx2048m -XX:MaxPermSize=512m" 

and restart your shell. Worked for me

Answer 2

This error is thrown by maven compiler plugin, Edit the pom file you are building, Under attribute maven-compiler-plugin add below configuration

 <configuration>
 <verbose>true</verbose>
 <fork>true</fork>
 </configuration>

This will clear heap space error.
