> Currently, if it is multiquery off mode, the pig script is executed whenever
> a STORE is encountered. This becomes even more inefficient in Tez as multiple
> DAGs are launched. And it is also not possible to do explain if multiquery is
> off because of this. Should switch to batch mode. Only difference should be
> that MultiQueryOptimizer is not applied in multiquery off mode.
