Appy created HBASE-20567:
----------------------------
Summary: Given both old and new descriptors to pre/post hooks of
modify operations for table and namespace
Key: HBASE-20567
URL: https://issues.apache.org/jira/browse/HBASE-20567
Project: HBase
Issue Type: Improvement
Reporter: Appy
In postModify* hooks like {{postModifyX(..., Descriptor newDesc)}}, there's no
way of getting the old descriptor which was there before modification happened.
Having both old and new descriptors will make the hooks more useful.
We felt the need when we wanted to audit certain events but there was no way of
deducing them by just seeing 'after-state' of modification.
To keep the method signatures consistent, i have modified both pre and post
hooks with new arguments which are well named and commented.
