部署Hadoop,需和Linux操作系统位数一致

本次实验的环境：linux 64位+hadoop2.7.2 64位.
HADOOP_HOME=/hadoop/hadoop-2.7

1. [root@sht-sgmhadoopnn-01 ~]# getconf LONG_BIT
   
2. 64
   
3. [root@sht-sgmhadoopnn-01 ~]# cd /hadoop/hadoop-2.7.2/lib/native/
   
4. [root@sht-sgmhadoopnn-01 native]# ll
   
5. total 4924
   
6. -rw-r--r-- 1 10011 10011 1382764 Jan 26 08:20 libhadoop.a
   
7. -rw-r--r-- 1 10011 10011 1632184 Jan 26 08:20 libhadooppipes.a

14. [root@sht-sgmhadoopnn-01 native]# file libhadoop.so.1.0.0
    
15. libhadoop.so.1.0.0: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, not stripped

  说明64位hadoop部署需在64位操作系统上,同理32位linux上应该部署32位hadoop.
