> The ColumnStatistics test failures are already known to fail in Windows. This is mostly a file size difference which is not a product issue and can be ignored safely. The reason for the failure is ORC stripe footer stores the timezone ID as string in stripe footer. Since Linux and Windows produces different timezone id string, the size of the stripe footer will change accordingly. Because of this timezone difference the file sizes will be different on windows and linux. We can either update the orc-file-has-null.out output file on Windows or ignore this test altogether.
