hadoop-2.5.0-cdh5.3.6 native包 替换

Posted 2023-01-04 yin1361866686

未替换前hadoop上操作会出现如下警告：

This script is Deprecated. Instead use stop-dfs.sh and stop-yarn.sh
18/01/02 03:01:03 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

 

解决：

　　1、下载编译好的native包，解压。

　　　　native包：https://files.cnblogs.com/files/yin1361866686/native-2.5.0.tar.gz

　　2、替换掉/hadoop/lin/native.

　　3、通过bin/hadoop checknative检验是否成功.
