> It is quite common to see header/footer lines in real world data set. So
> skipping first/last N lines in "create external table" DDL can be useful
> feature for Tajo users. In this way, user don't need additional processing
> of data which generated by other application with a header or footer and
> directly use the file for table operations.
> cf. Same feature added in Hive 0.13 :
