部署Hadoop,需和Linux作業系統位數一緻

本次實驗的環境：linux 64位+hadoop2.7.2 64位.

HADOOP_HOME=/hadoop/hadoop-2.7

點選(此處)折疊或打開

[root@sht-sgmhadoopnn-01 ~]# getconf LONG_BIT

64

[root@sht-sgmhadoopnn-01 ~]# cd /hadoop/hadoop-2.7.2/lib/native/

[root@sht-sgmhadoopnn-01 native]# ll

total 4924

-rw-r--r-- 1 10011 10011 1382764 Jan 26 08:20 libhadoop.a

[root@sht-sgmhadoopnn-01 native]# file libhadoop.so.1.0.0

libhadoop.so.1.0.0: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, not stripped

 說明64位hadoop部署需在64位作業系統上,同理32位linux上應該部署32位hadoop.
