Mac Local Installation standalone hadoop--learning notes

Mac Configuration Hadoop
1. Modify/etc/hosts
127.0.0.1 localhost
2. Download the hadoop2.9.0 and JDK and install the appropriate environment
Vim/etc/profile
Export hadoop_home=/users/yg/app/cluster/hadoop-2.9.0
Export hadoop_conf_dir= $HADOOP _home/etc/hadoop
Export path= $PATH: $HADOOP _home/bin
Export Java_home=/library/java/javavirtualmachines/jdk1.8.0_144.jdk/contents/home
Export path= $PATH: $JAVA _home/bin
3. Configure SSH (password-free login)
SSH-KEYGEN-T RSA generates public and private keys
Cat Xxx.pub >> Authorized_keys write the public key file into the Authorized_keys
chmod 644 Authorized_keys
SSH ip/hostname Test password-free login,
4. Installing Hadoop
Tar zxf hadoop-2.9.0.tar.gz Decompression
And then into the/etc/hadoop directory under the hadoop-2.9.0 directory.
