> Cleanup metadata of child views for a base table that has been dropped
> ----------------------------------------------------------------------
>
> Key: PHOENIX-4764
> URL: https://issues.apache.org/jira/browse/PHOENIX-4764
> Project: Phoenix
> Issue Type: Sub-task
> Reporter: Thomas D'Silva
> Assignee: Kadir OZDEMIR
> Priority: Major
>
> When we drop a base table, we no longer drop all the child view metadata.
> Clean up the child view metadata during compaction.
> If we try to recreate a base table that was previously dropped but whose
> child view metadata wasn't cleaned up throw an exception. Add a test for
> this.
