If the driver doesn't support this (at least for Apache Hive 1.2.1), it
will throw an exception, perhaps wrap these calls in a try/catch and ignore any
errors (as they would have been presented to the user via doc and validation)?

> With HIVE-4924 it is possible to set a query timeout when executing a query
> against Hive (starting with Hive 2.1). Right now, NiFi is built using Hive
> 1.2.1 and this feature is not available by default (the method is not
> implemented in the driver). However, if building NiFi with specific profiles
> this feature can be used.
> The objective is to expose the query timeout parameter in the processor and
> enable expression language. If the version of the driver is not implementing
> the query timeout the processor will be in invalid state (unless expression
> language is used, and in this case, the flow file will be routed to the
> failure relationship).
