Research direction
Start by reading pinot-core/src/main/java/org/apache/pinot/core/common/datatable/DataTableUtils.java around line 121 and compare how column types are determined for empty and non-empty results. Reproduce an empty-result query, then verify that its returned column types match the corresponding non-empty result types.
