解决方案：
1，
2、
3、
总结：
问题二：
create ‘t1’, ‘f1’, ‘f2’, ‘f3’
NameError: undefined local variable or method `?t1?' for main:Object
问题三：
http://master:60010/master-status 这个页面不能访问 报500等错误
最终解决方案：
http://master:50070/ 进入hdfs 页面管理
删除 /hbase/WALS 中所有文件 OK le
/hbase/oldWALS 中所有文件 OK le
或者执行命令：
hadoop fs -rm -R /hbase/WALS
hadoop fs -rm -R /hbase/oldWALS
