Hive documentation for "hive.execution.mode"

[#1]

Hi, The online documentation is missing the description for "hive.execution.mode" configuration parameter. Is this supposed to be an internal parameter? If not, could this be added to the documentation?

Yes it was missing, I've added it to the documentation; because it's needed to make llap work in the first place.
