> The schema written for maps isn't compatible between hive and pig. This means
> any files written in one cannot be properly read in the other.
> More specifically, for the same map column c1, parquet-pig generates schema:
> message pig_schema {
> optional group c1 (MAP) {
> repeated group map (MAP_KEY_VALUE) {
> required binary key (UTF8);
> optional binary value;
> }
> }
> }
> while parquet-hive generates schema:
> message hive_schema {
> optional group c1 (MAP_KEY_VALUE) {
> repeated group map {
> required binary key;
> optional binary value;
> }
> }
> }
