Duo Zhang commented on HBASE-25290:
-----------------------------------

Could we say no kerberos when 'single-user'/'maintenance-mode'?
{quote}
I'm afraid not. At least if the underlying HDFS needs kerberos then we need to
enable kerberos for HDFS client, it will be a cost to also redeploy the HDFS
cluster...
Anyway, will try to implement a prototype later, either by the mini cluster or
let me see if it is easier to just start a region server in the same process in
maintenance mode.
Or back to the root requirements here, do you think it is worth to undo HMaster
extends HRegionServer? I want to do it but after facing the maintenance mode
problem, I'm a bit uncertain about whether it is still worth to do.
Thanks.
