[hadoop] hadoop “util.NativeCodeLoader: Unable to load native-hadoop library for your platform”

执行

      bin/hdfs dfs -mkdir /user,创建目录时出现警告信息。

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

我这里用的是hadoop 2.6.4.

下载hadoop-native-64-2.6.0.tar:

http://dl.bintray.com/sequenceiq/sequenceiq-bin/hadoop-native-64-2.6.0.tar

下载完以后，解压到hadoop的native目录下，覆盖原有文件即可。操作如下：

tar -x hadoop-native-64-2.6.0.tar -C  hadoop/lib/native/

.

再次执行，成功。
