> Hive should be able to skip header and footer lines when reading data file
> from table. In this way, user don't need to processing data which generated
> by other application with a header or footer and directly use the file for
> table operations.
> To implement this, the idea is adding new properties in table descriptions to
> define the number of lines in header and footer and skip them when reading
> the record from record reader. An DDL example for creating a table with
> header and footer should be like this:
> {code}
> Create external table testtable (name string, message string) row format
> delimited fields terminated by '\t' lines terminated by '\n' location
> '/testtable' tblproperties ("skip.header.line.count"="1",
> "skip.footer.line.count"="2");
> {code}
