hadoop start-all.sh碰到的问题

我用的是centOS 学习hadoop，使用start-all.sh报如下错误：

This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh

It's highly recommended that you fix the library with 'execstack -c ', or link it with '-z noexecstack'.

解决方法：

修改/etc/profile
export HADOOP_HOME=你自己的hadoop目录
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_YARN_HOME=$HADOOP_HOME
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOOME/sbin:$HADOOP_HOME/lib
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"
