> Apache Calcite's tracing functionality plays an important role when we debug
> issues related to either logical planning or physical planning in Drill.
> However, since Drill-705 introduced a HepPlanner to do query planning for
> Window Function, the tracing functionality is broken.
> For instance, if I turn on Calcite tracing and set the tracing level to
> "FINER", as following:
> {code}
> org.apache.calcite.plan.RelOptPlanner.level = FINER
> {code}
> When submit a query to Drill, Drill hit AssertionError.
> {code}
> SYSTEM ERROR: java.lang.AssertionError: Internal error: should never get here
> [Error Id: 3410c3b4-726f-487b-a1c4-287b6ae724aa on 172.16.0.120:31010]
