前言

最近须要安装CDH4.5, 在重启后提示缺失native lib, 通过一番折腾后,终于安装成功,下面记录下native lib的获取过程.

1.相关环境

项	值
OS	Centos6.4
Arch	x86_64
Hadoop	hadoop-2.0.0-cdh4.5.0
[主]duangr-1	192.168.56.10
[主]duangr-2	192.168.56.11
[主]duangr-3	192.168.56.12

2.获取代码

• hadoop-2.0.0-cdh4.5.0.tar.gz

• hadoop-2.0.0+1518-1.cdh4.5.0.p0.24.el6.x86_64.rpm

3.安装hadoop

安装hadoop-2.0.0-cdh4.5.0.tar.gz, 此处略

4.安装Native Lib

将hadoop-2.0.0+1518-1.cdh4.5.0.p0.24.el6.x86_64.rpm在PC上使用压缩工具打开后,取出\usr\lib\hadoop\lib\native 下面的代码,上传到主机 ${HADOOP_HOME}/lib/native 下面

cd ${HADOOP_HOME}/lib/native
rm libhadoop.so
rm libsnappy.so
rm libsnappy.so.1
ln -s libhadoop.so.1.0.0 libhadoop.so
ln -s libsnappy.so.1.1.3 libsnappy.so.1
ln -s libsnappy.so.1.1.3 libsnappy.so

cd ..
tar -zcf native.tar.gz native

scp native.tar.gz duangr-2:${HADOOP_HOME}/lib
ssh duangr-2 "cd ${HADOOP_HOME}/lib; tar -zxf native.tar.gz;"

scp native.tar.gz duangr-3:${HADOOP_HOME}/lib
ssh duangr-3 "cd ${HADOOP_HOME}/lib; tar -zxf native.tar.gz;"

5.安装完成

重启hadoop便可
