Description

GroupMismatchException show in logs just when cluster starts

 

environment:

3C3D

GroupMismatchException show in both datanode and confignode logs just when cluster starts, the database is empty --no any database.

I'm quite sure that there is no data left before I start this iotdb cluster.

And this kind of logs are showed again and again.

 

Is there something left that it should be deleted?
