Eric Hanson commented on HIVE-5795:
-----------------------------------

Looks good, but there are a bunch of places where you need to modify your 
comments to obey Hive coding conventions -- 
https://cwiki.apache.org/confluence/display/Hive/HowToContribute --, especially 
for putting blank lines before comments, and also in a small number of places 
putting blanks between tokens.

> 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}
