Attila Szabo created SQOOP-3029:
Summary: Add an option for uppercase/lowercase column name mapping
between HCatalog and RDBMS cloumn name list
Issue Type: Improvement
Reporter: Attila Szabo
Fix For: 1.4.7
The current implementation of HCatalog related export works out of the box with
RDBMS systems (e.g. Oracle) if the column names match case sensitive, although
in several cases the column names are received as an UPPER_CASE list from the
RDBMS, and thus the export fails, within the ClassWriter.
Although the users have the possibility to define the name of the columns
explicit with the --columns option, in case of 100+ columns it's not practical.
It would be great to have an option which could do the matching in lower and
UPPER case as well. The start point for this implementation should start from
SqoopHCatUtilities#configureHCat method with respect to ensure HCatalog api is
able to handle the different cased column names.
