--------------------------------------------
Summary: Clarify patch upgrade compatibility guarantees
Key: HBASE-24955
URL: https://issues.apache.org/jira/browse/HBASE-24955
Project: HBase
Issue Type: Improvement
Components: documentation
Affects Versions: 3.0.0-alpha-1, 2.3.3, 1.7.0
Reporter: Bharath Vissapragada
Per the [compatibility|https://hbase.apache.org/book.html#hbase.versioning]
guidelines (specifically section "Client-Server wire protocol compatibility
") which says "We could only allow upgrading the server first. I.e. the server
would be backward compatible to an old client, that way new APIs are OK."
This gives an impression that it is fine to break API compatibility in patch
upgrades and expect the users to upgrade server binaries first before upgrading
clients. However, when considering a back-port of HBASE-24765, it was noted by
[~zhangduo] and [~ndimiduk] that this compatibility shouldn't be broken. Seems
like something that should be clarified in the docs.
