ASF GitHub Bot commented on DRILL-3993:

Github user vvysotskyi commented on the issue:

    @amansinha100, regarding HashAggregate OOM related change, it was done in the scope of
this pull request since with new Calcite a physical plan for the query was changed to the
correct one but it caused an infinite loop in HashAgg operator. Therefore I made these changes
in order to prevent this infinite loop for the queries that previously worked. 
    I still think that it is better to keep this change in this PR.
