hadoop2.5.2出现
WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform… using builtin-java classes where applicable

原因：因为我用的centos6.9，centos6的源最高到2.12，这里需要2.14

解决：

wget http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gztar zxvf glibc-2.14.tar.gzcd glibc-2.14mkdir buildcd build../configure --prefix=/usr/local/glibc-2.14makemake installln -sf /usr/local/glibc-2.14/lib/libc-2.14.so /lib64/libc.so.6
