It was because the program has applied the long, detailed header for formatted desc for column data. These tables have 12 data, but they are transposed, so at the end they have only 2 columns. Still they were given the schema containing the 12 columns at the fetch task, which led to these tables with many empty columns. It was fixed in this patch. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
