> There are two cases where the HashJoin Memory calculator over reserves memory:
>  1. It reserves a maximum incoming probe batch size during the build phase. This is not really necessary because we will not fetch probe data until the probe phase. We only have to account for the data received during OK_NEW_SCHEMA.
>  2. https://issues.apache.org/jira/browse/DRILL-6646
