Josh Elser commented on HBASE-18241:
------------------------------------
bq. Is it valid to change the Client API in a source compatible way for a major
version
If memory serves... I think you would need to leave
{{Admin#createTable(HTableDescriptor)}}, deprecate it, and then add the new API
{{Admin#createTable(TableDescriptor)}}.
If you removed the method completely, when clients upgrade from 1.x to 2.x,
their code would not directly work. The intent of semver for this circumstance
is that users code would still work from 1.x to 2.x, but is not guaranteed to
work for 3.x.
> Change client.Table, client.Admin, Region, and Store to not use
> HTableDescriptor or HColumnDescriptor
