Hbase启动时没有Hmaster进程

hbase(main):001:0> list
TABLE                                                                                                     

ERROR: Can't get master address from ZooKeeper; znode data == null

Here is some help for this command:
List all tables in hbase. Optional regular expression parameter could
be used to filter the output. Examples:

  hbase> list
  hbase> list 'abc.*'
  hbase> list 'ns:abc.*'
  hbase> list 'ns:.*'

解决：

这里问题主要是hbase没有正常启动起来，http://hadoop0:16010/master-status无法查看hbase状态，主要是因为hdfs端口配置错误，这里采用了帮助文档中的8020端口，实际上我的hdfs端口采用hadoop的默认9000端口，修改配置文件hbase-site.xml：

hbase.rootdir

hdfs://hadoop0:9000/hbase

     保存，并分发到各个节点，保持配置文件的一致，然后：
     启动Hbase , bin/start-hbase.sh

启动顺序：hadoop-->zookeeper-->hbase 

在hadoop0上启动hadoop集群：

/home/hadoop/hadoop-2.6.0/sbin/start-all.sh

在每一台机器上启动zookeeper：

/home/hadoop/zookeeper-3.4.6/bin/zkServer.sh start

在hadoop0上启动hbase集群：

/home/hadoop/hbase-1.0.1.1/bin/start-hbase.sh

        此时jps查看到各个进程均已经启动，http://hadoop0:16010/master-status可以查看hbase状态，运行hbase shell的list命令，工作正常，问题解决。
