-------------------------------------------
FYI [~yanxinyi] [~sukumaddineni] this one shouldn't be too much work once
[PHOENIX-6035|https://issues.apache.org/jira/browse/PHOENIX-6035] is finished
since it is basically going to run whatever changes we need in 6035 for the
upgrade path.
> Introduce a new statement to rollback Splittable SYSTEM.CATALOG changes when
> phoenix.allow.system.catalog.rollback=true
> -----------------------------------------------------------------------------------------------------------------------

> Key: PHOENIX-6036
> URL: https://issues.apache.org/jira/browse/PHOENIX-6036
> Project: Phoenix
> Issue Type: Improvement
> Affects Versions: 5.0.0, 4.15.0
> Reporter: Chinmay Kulkarni
> Priority: Major
> Fix For: 5.1.0, 4.16.0
>
>
> Setting phoenix.allow.system.catalog.rollback=true makes it possible for the
> user to rollback changes introduced via Splittable SYSTEM.CATALOG. We
> however, do not have any command to do so and the operator is responsible
> for doing SYSTEM table surgeries via manual steps like UPSERT SELECT
> statements to move parent->child links, running all drop view commands queued
> in SYSTEM.TASK, etc. We should introduce a command to do this for the user
> automatically.
