Guanghao Zhang commented on HBASE-19861:
bq. Is this behaviour intentional?
Yes. backup master show nothing about tables.
bq. I think we should fall back to rpc based listing in case of backup master
and can have this improvement in case of active master.
The backup master may use a seperate UI based on rpc. No need active master
fall back to rpc.

Hi, now the backup master UI does not list any user tables. Is this behaviour
intentional?
