+1 for planning EOL support for HBase 1.3, but can we do it after 4.16 release? I feel it because of the following reasons:-
(including user <email@example.com
* It will be an advance notice to the users who have been waiting for fixes in 4.16
release for a long time but are on HBase-1.3.
* As work is already done to support 1.3 through shim, so why not release
it if it is possible with minimal effort.
* We will have code for 1.3 shim available in release tag, then in future,
if someone volunteers to support 1.3(for a minor release or 4.16 point release) doesn't
need to revert the set of commits which brings back this shim layer,
instead can use the tag and go with it.
