安装 hadoop 2.4.1 报错信息
WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
[root@db96 hadoop]# hadoop dfs -put ./in DEPRECATED: Use of this script to execute hdfs command is deprecated. Instead use the hdfs command for it. 14/07/17 17:07:22 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable put: `./in': No such file or directory
主要原因：

系统是 64位的，而hadoop2.4.1 是32 位的，需要重新安装一个64位的版本
[root@bogon native]# file libhadoop.so libhadoop.so: symbolic link to `libhadoop.so.1.0.0' [root@bogon 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, BuildID[sha1]=f10b72d3bd2583ab9b126ede6ca886c3c9cc8a88, not stripped [root@bogon native]#
替换成 hadoop2.7.1 版本没有问题
