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:.*'
hbase(main):002:0>

Zookeeper的2181端口拒绝hbase连接，导致hmaster启动后直接退出，不能正常启动；
exception：zookeeper.ClientCnxn: Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect java.net.ConnectException: 拒绝连接
我采用配置参数是hbase自带的Zookeeper，之前反复重启几次，会正常登陆，现在采用自己安装的Zookeeper，启动hbase，关闭Hbase的自带的开关：
修改 vi hbase-env.sh
128 # export HBASE_MANAGES_ZK=true //128行注释使用自己安装的Zookeeper，将Zookeeper的zoo.cfg 拷贝到 hbase目录下的conf目录中
cp ~/training/zookeeper-3.4.10/conf/zoo.cfg ~/training/hbase-1.3.1/conf/
接着先启动本地的Zookeeper，再启动hbase，接着登陆hbase shell 登陆成功；
[[email protected] zookeeper-3.4.10]# zkServer.sh start
[[email protected] zookeeper-3.4.10]# start-hbase.sh
[[email protected] zookeeper-3.4.10]# hbase shell
hbase(main):001:0> list
TABLE
emp
result
results
sss
students
word
6 row(s) in 0.3760 seconds
放弃本地的hbase 改用自己安装的hbase 可以暂时解决 hmaster 登陆闪退的情况
