stack commented on HBASE-3909:
------------------------------

bq. Yes, this patch misses backup master, we can fix it with other patch.

Yes.

bq. Yes, at first these are some settings will be lost, we will not have all settings take
effect dynamic.

Pardon me.  I don't follow.  We can't lose the setting of short circuit reads on reload of
configs.  Do you think this will happen?  Can we add unit tests to show server configs ride
across the reload of configs?  Thanks [~aoxiang]

> I'm sure this issue exists already, at least as part of the discussion around making
online schema edits possible, but no hard this having its own issue.  Ted started a conversation
on this topic up on dev and Todd suggested we lookd at how Hadoop did it over in HADOOP-7001
