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 rows when reading data file for > a table > ------------------------------------------------------------------------------------- > > Key: HIVE-5795 > URL: https://issues.apache.org/jira/browse/HIVE-5795 > Project: Hive > Issue Type: Bug > Reporter: Shuaishuai Nie > Assignee: Shuaishuai Nie > Attachments: HIVE-5795.1.patch, HIVE-5795.2.patch > > > 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} -- This message was sent by Atlassian JIRA (v6.1.4#6159)
