--------------------------------------
Summary: DROP TABLE and DROP VIEW commands fail to drop second or
higher level child views
Key: PHOENIX-5247
URL: https://issues.apache.org/jira/browse/PHOENIX-5247
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.14.2
Reporter: Kadir OZDEMIR
Assignee: Kadir OZDEMIR
Fix For: 4.14.2
We have seen large number of orphan views in our production environments. The
method (doDropTable) that is used to drop tables and views drops only the first
level child views of tables. This seems to be the main root cause for orphan
views. doDropTable() is recursive only when the table type is TABLE or SYSTEM.
The table type for views is VIEW. The findChildViews method returns the first
level child views. So, doDropTable ignores dropping views of views (i.e.,
second or higher level views).
