> 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.number"="1", "skip.footer.number"="2");
> {code}
