> When CombineHiveInputFormat is used, it's possible that two files with different numbers of files can be included in the same split, in which case Hive will fail at one of several points with an ArrayIndexOutOfBoundsException.
> This can happen when a partition contains empty files or two partitions are read with different numbers of columns.
