compile hadoop-2.5.x on OS X(macbook)

  same as compile hbase ,it 's necessary for u to compile your own dist of hadoop to get best performance specified to your hardwares.

  bellow are some steps needed by this theme:

1.install some tools 

   a.cmake 2.6+

      download and set the path variable 

      this is used only if u want to make with native option,same like:

 

 mvn package -Pdist,native -DskipTests=true  -Dmaven.javadoc.skip=true

 

 

   b.protobuf  2.5+

     download and set variable

   c.mavn 3.0+

    same as above

 

2.comile hadoop by issuing

 

 mvn package -Pdist,native -DskipTests=true  -Dmaven.javadoc.skip=true -Dtar

 the results will like below:

main:
     [exec] $ tar cf hadoop-2.5.2.tar hadoop-2.5.2
     [exec] $ gzip -f hadoop-2.5.2.tar
     [exec] 
     [exec] Hadoop dist tar available at: /home/xxx/build-hadoop/hadoop-2.5.2-src/hadoop-dist/target/hadoop-2.5.2.tar.gz

3.problems

a.Exception in thread "main" java.lang.AssertionError: Missing tools.jar at: /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/Classes/classes.jar. Expression: file.exists()

  this is as the compiler needs a file named tools.jar but localted at classes.jar under dir Classes but found nothing.so u can do workaround:

  

cd `java_home`/
mkdir Classes
cd Classes
ln -s ../lib/tools.jar classes.jar

   but u should know,in macbook,the command 'ln' is ONLY effect when u locate in the target dir,otherwise u will see:

  

cd `java_home`
mkdir Classes
ln -s lib/tools.jar Classes/classes.jar
# or:ln -s lib/tools.jar /absolute/path/to/Classes/classes.jar
cp Classes/classes.jar /tmp
Error:no such file or dir found

 

2.failed to compile target:hadoop mavn doc

   this is not important for this theme,so u can add a param to ignore it:

-Dmaven.javadoc.skip=true
