Description

If a DROP VIEW command is issued against a non-existent view, it fails with an error indicating issue with ZK connection:

> drop view customer_address ;
+------------+------------+
|     ok     |  summary   |
+------------+------------+
| false      | Error: Failure while accessing Zookeeper. KeeperErrorCode = NoNode for /drill/storage.views.dfs.tpcds_text_sf1/customer_address |
+------------+------------+
1 row selected (0.058 seconds)

The error message must clearly indicate that the view does not exist.
