Let's see the document. -- Required?
1. java install & set the environment variable JAVA_HOME in your OS. 2. ssh install in your OS. -- Are you ready? 3. download the hadoop. 4. edit the conf/hadoop-env.sh, set JAVA_HOME in conf/hadoop-env.sh. 5. edit the configuration files. -- Execution? 6. hadoop FS format & start. BTW, Jason, Why you recommend the set JAVA_HOME in hadoop-env.sh at first level? Thanks.
