>             Project: Hive
>          Issue Type: Bug
>          Components: Physical Optimizer, Tez
>    Affects Versions: 1.2.0
>            Reporter: Gopal V
>            Assignee: Gopal V

> TezCompiler::runDynamicPartitionPruning() & ppr.PartitionPruner() calls the graph
walker even if all tables provided to the optimizer are unpartitioned (or temporary) tables.
> This makes it extremely slow as it will walk & inspect a large/complex FilterOperator
later in the pipeline.
