bin/hdfs dfs命令存在WARN util.NativeCodeLoader问题消除方法

例如：
[hadoop@db01 hadoop-2.5.0]$ bin/hdfs dfs -ls
17/03/01 21:50:33 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Found 1 items  --------------------------------------------------------------------------->这个警告需要编译源码包并替换lib/native包才能消除
