【问题2】Error contacting service. It is probably notrunning.
1）查看zoopkeeper.out

【错误2解决】没有将zookeeper复制到其他的节点！！！
没有在每个节点启动zookeeper
6.安装配置Hbase集群 a>启动HDFS集群实例,并创建目录##hdfs://master01:54310/hbase【注意与Hadoop，core-site.xml中的fs.default.name中的端口号保持一致，统一设置为54310；hbase-site.xml中的hbase:rootdir中的端口号】
hduser@master:/usr/local/hadoop$bin/hadoop fs -mkdir /hbase
