2、opSoftware/hadoop-1.0.4/conf/mapred-site.xml52.6修改/root/hadoopSoftware/hadoop-1.0.4/conf/masters62.7修改/root/hadoopSoftware/hadoop-1.0.4/conf/slaves62.8修改/root/hadoop-1.0.4/conf/hadoop-env.xml62.9同步到所有节点：72.10启动hadoop73Hbase安装73.1修改主节点hbase/conf文件夹下的hbase-env73.2修改主节点conf内的hbase-site

3、.xml文件73.3修改regionservers文件为83.4同步到所有从节点93.5启动hbase91.ssh无密钥访问1.1修改每台机器上的/etc/hosts，改为192.168.36.86BG4S02主节点192.168.36.92BG8S01从节点192.168.36.93BG8S02从节点192.168.36.94BG8S03从节点192.168.36.95BG8S04从节点192.168.36.96BG8S05从节点192.168.36.97BG8S06从节点192.168.36.98BG8S07从节点192.168.36.87BG8S08从节

4、点1.2在每台机器上安装sshssh-keygen-trsa,一直按回车，指导最后。把所有从节点台的id_rsa.pub拷贝到主节点的/root/.ssh/的目录下：scpBG8S01:/root/.ssh/id_rsa.pub/root/.ssh/id_rsaBG8S01.pubscpBG8S02:/root/.ssh/id_rsa.pub/root/.ssh/id_rsaBG8S02.pubscpBG8S03:/root/.ssh/id_rsa.pub/root/.ssh/id_rsaBG8S03.pubscpBG8S04:/root/.ssh/id_rs
