问题1:
hbase保存, 压缩引起的
解决办法:
查看dfs模式,果然是安全模式
grid@master1:~$ hadoop dfsadmin -safemode get
Safe mode is ON
关闭dfs安全模式
grid@master1:~$ hadoop dfsadmin -safemode leave
Safe mode is OFF
再次启动Hbase,能正常启动
:::::::::
问题2:
hbase没有master节点:
重启hbase
问题3:

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:.*'
多重启几次就好了。。。。。。。。 5次以下, 超过5次就不是这个问题
