Sushanth Sowmyan commented on HCATALOG-259:
-------------------------------------------

I'm torn between the notion of somewhat breaking backward compatibility by 
making the HCatalog users change code, and the simplicity of the first approach.

I think that given that there aren't thaaat many users of HCat yet, it's easy 
to provide a utility method that simply does a new 
DefaultHCatRecord(lazyRecord.getAll()). So it's a +1 for (1) from me.
                
> Make readFields() and write() in LazyHCatRecord work

> With the recent changes in HCATALOG-241, write() and readFields() will no 
> longer work.  This will cause a problem for MR users who want to filter out 
> records in their map job and then write the records back out to go to the 
> reduce, or to be saved on disk.
