hbase所遇问题

时间 2020-12-31

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

[email protected]:~$ hadoop dfsadmin -safemode get 
Safe mode is ON

关闭dfs安全模式

[email protected]:~$ 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
