Enis Soztutar commented on HBASE-7848:
--------------------------------------
bq. I'm thinking about why we only do this on the enabled table snapshot but
not on the disabled table snapshot. I think we would want to block the enables
(or enables and then alters) from happening while a disabled table snapshot is
happening.
If there is no other guard against taking a snapshot and enabling the table, it
makes sense to acquire a table lock.
> Use ZK-based read/write lock to make flush-type snapshot robust against table
> enable/disable/alter
