It says you have not started the hbase master. Once you restarted the system have you confirmed whether all hadoop daemons are running? sudo jps If you are using CDH package then you can automatically start the hadoop daemons on boot using reconfig package.

The HBase/Hadoop were installed correctly. It also ran well with my Java code. However, if after shutting down the server for some time, for example, four or five days, I noticed that HBase/Hadoop got a problem. I got an ERROR when typing "status" in the shell of HBase. ERROR: org.apache.hadoop.hbase.MasterNotRunningException: Retried 7 times Such a problem had happened for three times in the three weeks. The HBase/Hadoop are installed on Ubuntu 10. Have you encountered such a problem? How to solve it? Thanks so much! Best regards, Bing
