    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。
根据所使用的系统帐号编辑:vi /etc/profile或者vi ~/.bash_profile
在文档的末尾添加如下代码:

    export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
    export HADOOP_OPTS=”-Djava.library.path=$HADOOP_HOME/lib”

然后用source /etc/profile或者source ~/.bash_profile重新使之生效即可!
