             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).
