[root@hadoop sbin]$ sbin/start-dfs.sh
1WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-Java classes where applicable
解决方法
1.去网站:http://dl.bintray.com/sequenceiq/sequenceiq-bin/ 下载对应的编译版本,我下载的是2.6
2.将准好的64位的lib包解压到已经安装好的hadoop安装目录的lib/native 和 lib目录下
[root@hadoop hadoop]tar -xvf hadoop-native-64-2.6.0.tar -C hadoop/lib/native[root@hadoop hadoop]tar -xvf hadoop-native-64-2.6.0.tar -C hadoop/lib
2.修改/etc/profile,在里面添加
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"
之后问题解决
