前言

最近須要安裝CDH4.5, 在重啓後提示缺失native lib, 通過一番折騰後,終於安裝成功,下面記錄下native lib的獲取過程.

1.相關環境

項	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.獲取代碼

• 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.安裝hadoop

安裝hadoop-2.0.0-cdh4.5.0.tar.gz, 此處略

4.安裝Native Lib

將hadoop-2.0.0+1518-1.cdh4.5.0.p0.24.el6.x86_64.rpm在PC上使用壓縮工具打開後,取出\usr\lib\hadoop\lib\native 下面的代碼,上傳到主機 ${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.安裝完成

重啓hadoop便可
