Solution:

1, in the development machine host file configuration, that is, C:\Windows\System32\drivers\etc directory

192.168.182.128 caobg (hbase master running machine name)

View the vim /etc/hosts file

127.0.0.1 caobg localhost localhost4 localhost4.localdomain4

::1 caobg localhost6 localhost6.localdomain6

caobg can be found bound to ip address 127.0.0.1

3. Remove CAOBG

127.0.0.1 localhost localhost4 localhost4.localdomain4

::1 localhost6 localhost6.localdomain6

4. Restart cluster and solve problem
