>                 Key: HIVE-10175
>                 URL: https://issues.apache.org/jira/browse/HIVE-10175
>             Project: Hive
>          Issue Type: Bug
>          Components: Query Planning, Tez
>    Affects Versions: 1.2.0
>            Reporter: Gopal V
>            Priority: Minor
>
> TezCompiler::runDynamicPartitionPruning() calls the graph walker even if all tables provided to the optimizer are unpartitioned temporary tables.
> This makes it extremely slow as it will walk & inspect a large/complex FilterOperator later in the pipeline.
