Subject Re: [DISCUSS] EOL support for HBase 1.3
Date Tue, 25 Aug 2020 01:15:57 GMT
+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 <> )

* 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.
