00-02        SelectionVectorRemover
00-03          Sort(sort0=[$0], dir0=[ASC])
00-04            Project(a1=[$0], EXPR$1=[$1])
00-05              HashAgg(group=[{0}], EXPR$1=[COUNT()])
00-06                Project($f1=[$0])
00-07                  HashJoin(condition=[=($1, $2)], joinType=[inner])
00-09                    Project($f1=[$0], $f2=[$0])
00-11                      Scan(groupscan=[ParquetGroupScan [entries=[ReadEntryWithPath [path=maprfs:/aggregation/t1]], selectionRoot=/aggregation/t1, numFiles=1, columns=[`a1`]]])
00-08                    HashAgg(group=[{0}])
00-10                      StreamAgg(group=[{}], EXPR$0=[MIN($0)])
00-12                        Scan(groupscan=[ParquetGroupScan [entries=[ReadEntryWithPath [path=maprfs:/aggregation/t2]], selectionRoot=/aggregation/t2, numFiles=1, columns=[`a2`]]])
{code}

I'm choosing "Execution-general" component, because query plan at the first glance looks correct.
