Subject Selective updates using HCatOutputFormat.setSchema()?
Date Thu, 03 Nov 2011 21:57:24 GMT
Hi,

I'd like to clarify wether this selective column updates are supported as part of HCatOutputFormat.setSchema().

If I have an unpartitioned table:

foo(int col1, int col2, int col3)

Would it be possible for me to just pass column "col2" when calling setSchema? For columnar
stores (ie Hbase) it would be more efficient just to write out the values that we want updated
instead of the entire row.

-Francis
