Shashikant Banerjee commented on RATIS-924:
-------------------------------------------
Currently, even if a raft group is removed, the raft log directory is not
cleaned up. As a result, when datanode restarts it still reinitializes the raft
group as it finds the raft group dir intact. I think we should do the following:
1) Add an config to selectively delete/retain the raft group dir on group remove
2) If the deleteDirectory config is set to false, it should rename the dir so
that the next restart, reinitialisation doesn't happen
> rename raft group dir on disk when remove group is invoked
> ----------------------------------------------------------
