前一篇的问题解决了，是 hbase 下面lib 包的jar问题，之前写MR的时候加错了包，替换掉了原来的包后出现另一问题：
@ubuntu:/home/hadoop/hbase-0.94.6-cdh4.5.0/bin$ ./start-hbase.sh 
starting master, logging to /home/hadoop/hbase-0.94.6-cdh4.5.0/logs/hbase-master-ubuntu.out
localhost: starting regionserver, logging to /home/hadoop/hbase-0.94.6-cdh4.5.0/logs/hbase-regionserver-ubuntu.out
后 jps 进程没有出现HMaster进程。
错误日志：如下
