Hi Stack, Thanks for the reply! I just want to clarify this:
API is a constant inside a major version, 1.x or 2.x, etc., but can change across major versions. In HBase, are Major versions things like 1.1 and 1.2? I'm used to major version being the number to the left of the decimal, so that 1.2 and 2.3 are different Major versions, while 1.2 and 1.3 are different minor versions of the same major versions. That is, build versions are of the form Major.Minor.buildversion Am I misunderstanding? -Carol P. --------------------------------------------------------------- Email: [email protected] Twitter: @CarolP222 --------------------------------------------------------------- On Wed, Mar 30, 2016 at 11:52 AM, Stack <[email protected]> wrote: > On Wed, Mar 30, 2016 at 9:25 AM, Gunnar Tapper <[email protected]> > wrote: > >> An API that wraps the new API with the old interface thereby ensuring >> that clients don't have to change just because the underlying software >> changed. >> > > No. > > API is a constant inside a major version, 1.x or 2.x, etc., but can change > across major versions.
