配置hadoop jdk环境变量

修改etc/hadoop/hadoop-env.sh yarn-env.sh javahome例如：export JAVA_HOME=/usr/local/jrockit-jdk1.6.0_29

修改etc/hadoop/slaves文件,单点则直接配置该机器hostname

单机无密码登录

使用默认即可

执行命令

hadoop namenode -format

(正常情况下直接成功，没有提示输入y or n，若不成功共删除相关文件，例如/usr/local/hadoop下文件清空)

启动：

sbin/start-all.sh

Start a standalone WebAppProxy server. If multiple servers are used with load balancing it should be run on each of them:

$ $HADOOP_YARN_HOME/sbin/yarn-daemon.sh start proxyserver --config $HADOOP_CONF_DIR

Start the MapReduce JobHistory Server with the following command, run on the designated server:

$ $HADOOP_PREFIX/sbin/mr-jobhistory-daemon.sh start historyserver --config $HADOOP_CONF_DIR

7540 WebAppProxyServer

7628 JobHistoryServer

JobHistoryServer开启后可查看历史任务日志http://qiulp:19888/jobhistory
