> 1) Start the HBase server with 4.15.0 Phoenix
> 2) Connect with a 4.15.0 client
> 3) Create a base table and a view on top of the base table and create an index on top of this view:
> {code:sql}
> CREATE TABLE IF NOT EXISTS Z_BASE_TABLE (ID INTEGER NOT NULL PRIMARY KEY, HOST VARCHAR(10), FLAG BOOLEAN);
> CREATE VIEW Z_VIEW1 (col1 INTEGER, col2 INTEGER, col3 INTEGER, col4 INTEGER, col5 INTEGER) AS SELECT * FROM Z_BASE_TABLE WHERE ID>10;
> CREATE INDEX V_I ON Z_VIEW1(COL4);
> {code}
> 4) Drop the base table with the cascade option:
> {code:sql}
> DROP TABLE Z_BASE_TABLE CASCADE;
> {code}
> 5) DropChildViewsTask gets added to the SYSTEM.TASK table as expected, but when it gets scheduled and subsequently executed, it fails with the following exception:
> {code:java}

> Note that this marks the DropChildViews task for the base table as failed and so *if the base table has any other views, those views will also not be dropped*.
