Subject [jira] [Commented] (HIVE-16188) beeline should block the connection if given invalid database name.

Vihang Karajgaonkar commented on HIVE-16188:
--------------------------------------------

I looked into code again and I think client side is better place to handle this validation
than on the HiveServer2 side. In addition to this check in HiveSession I think we should also
add this check in HiveDriver:parseURLforPropertyInfo() method. Since we know that connection
request will fail there is no need to even attempt making a connection. What do you think
[~stakiar]?

> When using beeline shell to connect to HS2 or impalaD as below -
> Connection to HS2 using beeline tool on port 10000 -
> beeline -u "jdbc:hive2://HS2-host-name:10000/default;principal=hive/HS2-host-name@DOMAIN.EXAMPLE.COM"
> Connection to ImpalaD using beeline tool on port 21050 -
> beeline -u "jdbc:hive2://impalad-host-name.com:21050/XXX;principal=impala/impalad-host-name.com@DOMAIN.EXAMPLE.COM"

> Providing a invalid database name as XXX - the connection is made.
> It should ideally stop the connection to be successfull.
> Even though, the beeline tool does not allow to move forward, unless you provide a valid
DB name, like
> Use <Database-Name>;
