Chia-Ping Tsai commented on HBASE-19702:
----------------------------------------
bq. When servers is not null, addAll(servers) tries to add all items in servers
again. Seems not needed
nice catch.
bq. new TreeSet<>(tables) has no null check on tables. The constructor of
TreeSet does not do the null check either. It leads to NullPointerException if
tables is null
agreed.
> Improve RSGroupInfo constructor
