Keith Turner commented on ACCUMULO-456:
---------------------------------------
The patch depends on a table being in the offline state. It relies on the user
to keep the table in the offline state while the distcp runs. I was thinking
about a new table state, call this state FROZEN. A frozen table can be read,
but never written to. A FROZEN table can not transition to ONLINE, it can only
transition to DELETED. So a user could clone a table and then tranistion it to
FROZEN instead of OFFLINE. I like this because it makes the users intent for a
table very clear on a system with many users. I don't like that it adds
complexity to the system. If someone brings a table online while the distcp is
running, the distcp may fail which is probably not too big of a deal.
