Jonathan Hsieh commented on HBASE-7848:
---------------------------------------
I'm in the process of distilling the semantics of HBASE-7305. It seems that
all table ops currently take the write lock but I think we'll just need the
read table lock. We'd add a prepare call that takes the read lock of a source
table when calling TakeSnapshotHandler, and a release in the completeSnapshot
call.
