Feng Honghua commented on HBASE-9466:
-------------------------------------
[~jdcryans] Yes, I'm proposing a 'read-only mode'(can be per-table or
per-cluster) rather than 'disabling table', the latter is pretty heavyweight in
that it needs to offline all regions of the given table.
If we just want to temporarily disable 'update' to a table or the whole cluster
and later on we want to enable 'update' again, disabling a table or all tables
of the cluster seems a quite heavy choice.
Thanks for pointing me to the read-only interface of HTableDescriptor of trunk,
but I don't see any code using it, how is this RO expected to work?

> 2. it can serve read requests
