Unable to load native-hadoop library for your platform... using builtin-java cl

Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

在配置的时候，频繁出现这个问题，在网上找了相关资料，都是说libray包没找到。

检查所有配置，一切都正常。都配置正常。

修改过：etc/profile

问题还是没解决。

 

之后尝试如下步骤：

1， 开启调试日志 export HADOOP_ROOT_LOGGER=DEBUG,console

2，/data/server/hadoop-2.6.0/bin 

   ./hadoop checknative -a

查看日志，报如下错误：

[hadoop@DEV-NEW-HADOOP-01 bin]$ ./hadoop checknative

查看环境变量，并没有配置 java.library.path=:/data/server/hadoop-2.6.0/lib/native/Linux-amd64-64/。

之后，尝试使用：export JAVA_LIBRARY_PATH=$JAVA_LIBRARY_PATH:/data/server/hadoop-2.6.0/lib/native/

然后在检查：./hadoop checknative

恢复正常，问题解决
