Hey Mayank - I've looked briefly at case-sensitivity in Hive, and there's a lot of places where fields are lowercased to normalize. For HCatalog, I'm playing around with a small patch that makes case-sensitivity optional and it works if you run queries with Pig/HCat against the metastore. It would be a pretty large patch to make hive optionally case sensitive though.
Case sensitive field names as an option certainly would use helpful though. --travis On Tue, Aug 14, 2012 at 8:24 AM, Mayank Bansal <mayank.ban...@mu-sigma.com>wrote: > Hi,**** > > ** ** > > The column names in hive are by default case insensitive.**** > > I was wondering if there is any way, I could make the column names case > sensitive?**** > > I am running a model on a data, the data is now stored in hive, the model > has columns referred in camel case.**** > > It would require a lot of effort to change the code of the model, so I was > wondering if I could change my hive schema or anything.**** > > Would changing the metastore_db help in someway ?**** > > ** ** > > Thanks,**** > > Mayank**** > > ** ** > > ------------------------------ > This email message may contain proprietary, private and confidential > information.
