> 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).
