I tried and really it did not add any value and just added more code. The
methods includes 80 lines, and 10 of them are comments and 8 of them are "}".
There are two method calls take 12 lines because they have 6 arguments and each
argument is written on a separate line. I do not see what bothers you here. You
can break into tiny methods, such as createBaseTable, createViews,
dropBaseTable, and waitForViewsToDrop, if these methods are used by other test
methods. At this moment, there is only one test method.
> 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.
