升级glibc解决GLIBC_2.14 not found
使用hadoop命令时候，总会遇到GLIBC_2.14 not found 如下提示，需要升级glibc的版本
WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
在log4j里面添加加载项的debug日志
# vim /usr/local/hadoop/etc/hadoop/log4j.properties
log4j.logger.org.apache.hadoop.util.NativeCodeLoader=DEBUG
# start-dfs.sh
DEBUG util.NativeCodeLoader: Trying to load the custom-built native-hadoop library...
DEBUG util.NativeCodeLoader: Failed to load native-hadoop with error: java.lang.UnsatisfiedLinkError: /usr/local/hadoop-2.6.4/lib/native/libhadoop.so.1.0.0: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /usr/local/hadoop-2.6.4/lib/native/libhadoop.so.1.0.0)

得到提示GLIBC_2.14木有找到，需要安装高版本的glibc以解决问题
1，查看现在系统的glibc版本
# strings /lib64/libc.so.6 |grep GLIBC_
GLIBC_2.2.5
GLIBC_2.2.6
GLIBC_2.3
GLIBC_2.3.2
GLIBC_2.3.3
GLIBC_2.3.4
GLIBC_2.4
GLIBC_2.5
GLIBC_2.6
GLIBC_2.7
GLIBC_2.8
GLIBC_2.9
GLIBC_2.10
GLIBC_2.11
GLIBC_2.12
GLIBC_PRIVATE
2，安装glibc 2.19版本
wget http://mirrors.ustc.edu.cn/gnu/libc/glibc-2.19.tar.xz
tar -xf glibc-2.19.tar.xz
mkdir glibc-2.19/build
cd glibc-2.19/build
../configure --prefix=/usr --enable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
make -j2
make install
#安装完毕
ldconfig
# ll /lib64/libc*

因为glibc版本问题hadoop或者adb的使用都会有遇到，记下来以供分享
