Problems with Hadoop start-all.sh

I'm using CentOS to learn Hadoop, using start-all.sh to report the following error:

This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh 17/08/27 04:25:26 WARN util. nativecodeloader:unable to load Native-hadoop library for your platform ... using Builtin-java classes where applicable St Arting namenodes on [Java HotSpot (TM) Client VM warning:you has loaded library/home/hadoop/apps/hadoop-2.6.4/lib/native /libhadoop.so.1.0.0 which might has disabled stack guard.

Workaround:

export hadoop_home= your own HADOOP directory
export hadoop_common_home= $HADOOP _home
export Hadoop_ Hdfs_home= $HADOOP _home
export hadoop_mapred_home= $HADOOP _home

Export hadoop_conf_dir= $HADOOP _home/etc/hadoop
