[root@hd-m1 /]# ./hadoop/hadoop-2.6.0/sbin/start-all.sh 
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh

解决办法：

出现上述问题主要是环境变量没设置好，在~/.bash_profile或者/etc/profile中加入以下语句就没问题了。

　　#vi /etc/profile或者vi ~/.bash_profile
　　　　export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
　　　　export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"

然后用source重新编译使之生效即可！
　　#source /etc/profile或者source ~/.bash_profile
