hadoop-2.6.0在64位系统编译问题

问题：

[root@lsn-linux hadoop-2.6.0]# hadoop fs -ls /
14/12/09 19:43:06 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
[root@lsn-linux hadoop-2.6.0]#

原因是hadoop-2.6.0.tar.gz安装包是在32位机器上编译的，64位的机器加载本地库.so文件时出错，不影响使用。

解决：
1、重新编译源码后将新的lib/native替换到集群中原来的lib/native
2、修改hadoop-env.sh ，增加
export HADOOP_OPTS="-Djava.library.path=$HADOOP_PREFIX/lib:$HADOOP_PREFIX/lib/native"


编译前  请参考文档：Hadoop-2.6.0在Centos6.5 64位系统编译前准备工作

You have new mail in /var/spool/mail/root


问题产生的原因是：
     1、配有安装apache-ant。
     2、 Error while executing the compiler. InvocationTargetException: Java heap space ->   是由于 Apache-maven的 JVM问题，需要调整
         export MAVEN_OPTS="-Xms256m -Xmx512m"
