运行hbase时出现下面问题:

[hadoop@Masterpc hadoop]$ hbase shell

HBase Shell; enter 'help<RETURN>' for list of supported commands.

Type "exit<RETURN>" to leave the HBase Shell

Version 0.94.12, r1524863, Fri Sep 20 04:44:41 UTC 2013

hbase(main):001:0> status

15/03/10 11:19:04 ERROR client.HConnectionManager$HConnectionImplementation: Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

15/03/10 11:19:06 ERROR client.HConnectionManager$HConnectionImplementation: Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

。。。。。。。（省）

ERROR: org.apache.hadoop.hbase.MasterNotRunningException: Retried 7 times

Here is some help for this command:

Show cluster status. Can be 'summary', 'simple', or 'detailed'. The

default is 'summary'. Examples:

hbase> status

hbase> status 'simple'

hbase> status 'summary'

hbase> status 'detailed'

一种解决方法：查看占用端口2181的进程：

然后把占用的进程删除，然后重新启动：

然后分别进行：

[hadoop@Masterpc ~]$ start-all.sh 启动hadoop

[hadoop@Masterpc ~]$ start-hbase.sh 启动hbase

然后进行hbase操作：显示正常工作

[hadoop@Masterpc ~]$ hbase shell

HBase Shell; enter 'help<RETURN>' for list of supported commands.

Type "exit<RETURN>" to leave the HBase Shell
