deprecated nextColumnsBatch in RCFile.Reader

Hi,

Does anyone know why nextColumnsBatch() in RCFile.Reader has been deprecated? I'd like to write a MapReduce where the mapper receives an entire column at a time (more specifically, the key is the column ID and the value is the column values for that row batch). Using getColumn() and nextColumnsBatch() seems like the natural choice. Any pointers are appreciated.

Thanks,
Marwan
