Nick Dimiduk commented on HBASE-25875:
--------------------------------------
FYI [~pankajkumar] it is our project to apply changes to master and work our
way backwards. To that effect, in order for a change to release on branch-2.3,
it must be on branch-2.4. The only exceptions we have to this practice are for
changes that are not applicable to the newer release lines, for example, bug
fixes to features that have been removed in newer versions.
