Subject [jira] Commented: (HIVE-1216) Show the row with error in mapper/reducer
Date Fri, 05 Mar 2010 18:50:27 GMT


Zheng Shao commented on HIVE-1216:

Thanks for the link Jeff. This JIRA aims to do a bit different thing.
Instead of writing the data into _skip file and letting the job finish, we will print out
the row to stderr/stdout or just using LOG.

The advantage of this:
1. Really easy for debugging - people don't need to use command line tools to fetch the _skip
2. Should be able to attach column names with their values, because Hive knows the column

that caused error.
