解决办法：
（1）启动Hadoop的namenode
hadoop namenode -format（2）查看HBase的/conf/hbase-site.xml文件
[root@master conf]# vim hbase-site.xml看看下图的文件路劲是否有文件夹，文件夹下是否有数据，有数据就删掉，没有就新建这个文件夹。
[root@master conf]# cd ~
[root@master ~]# pwd
[root@master ~]# ls
anaconda-ks.cfg install.log install.log.syslog workspace
[root@master ~]# mkdir hbase/
[root@master ~]# ls
anaconda-ks.cfg hbase install.log install.log.syslog workspace
[root@master ~]#
（3）启动HBase
[root@master hbase-0.98.7-hadoop2]# bin/start-hbase.sh
master: zookeeper running as process 4846. Stop it first.
master running as process 4913. Stop it first.
