Benoit Sigoure updated HBASE-3174:
----------------------------------
Hadoop Flags: [Incompatible change, Reviewed] (was: [Reviewed])
The revision r1029115 (or
[08e64aae|https://github.com/apache/hbase/commit/08e64aaeadfadeee5534726b561431a88082b1f1#L1R374]
in Git) committed for this issue changes the on-write protocol in a
non-backwards compatible way. The change isn't listed in the release notes as
being incompatible. The Get serialization has a {{GET_VERSION}}, which right
now seems like just a waste of space.
In the future, I encourage you to be more careful about incompatible changes,
mark them as such properly, and document them in a more readable fashion when
making a release (you can't rely expect people to manually go through all the
issues listed in {{CHANGES.txt}} to see which one change the RPC protocol vs
something else).
This change could also have been introduced in a backwards compatible fashion.
Please keep this in mind for future changes.
As HBase becomes a more mature project, these considerations become extremely
important. Thank you.

> The public Get API does not currently support enabling/disabling the block

> converted into Scans this should be fairly trivial.
