Also agree with that. This is where my knowledge could be better, but I know I have seen it in the past where some Parquet files were written in a way that Impala could read them but Hive could not. As much as possible it seems good to avoid that. I'm not sure what the least common denominator/safest way to write would be. Maybe you have more experience with that, Mark?
Regardless of what writes the Parquet files I think it's not a bad design goal to have them be as broadly readable as possible (eg. if we do use Impala to write them, it would be good to have them still readable by Spark, Hive, etc.) Michael On Mon, Apr 17, 2017 at 4:12 PM, Mark Grover <[email protected]> wrote: > Thanks all your opinion. > > I think it's good to consider two things: > 1.
