> I created the following 2 views on 2 separate schemas.

> +---------------+--------------+------------+-----------------+

> | DRILL         | dfs.tmp      | case_customer | SELECT `columns`[0], `columns`[1] FROM

> 1 row selected (0.145 seconds)
> {code}
> Now, when I try to drop again it should say something like "No view by the name case_customer
found in the current workspace." Rather it throws the below.
> {code}
> 0: jdbc:drill:zk=n67:5181> drop view case_customer;
> +------------+------------+
> |     ok     |  summary   |

> | false      | Error: Failure while accessing Zookeeper |
> +------------+------------+
> 1 row selected (0.126 seconds)
> {code}
> And all good as it should be when executed as below.
> {code}
> 0: jdbc:drill:zk=n67:5181> drop view dfs.tmp.`case_customer`;
> +------------+------------+
> |     ok     |  summary   |

> | true       | View 'case_customer' deleted successfully from 'dfs.tmp' schema |
> +------------+------------+
> 1 row selected (0.11 seconds)
