    @pvillard31 Mind doing a rebase here, and updating the QUERY_TIMEOUT property to use FlowFile Attribute scope? I pushed up a rebased branch with the additional commit (https://github.com/mattyb149/nifi/commit/40b9d1db89168fac08f343be772516132f1f67c0) but I don't know if you can cherry-pick from there or if you have to do your own rebase, then cherry-pick my additional commit (if you want to use it of course).

> 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).
