Alex Levenson commented on PARQUET-275:
---------------------------------------
Looks like I even documented that the key can't be partially projected here:
https://github.com/apache/parquet-mr/blame/b8aae90d333094da4afd65ad5f5eb13854811f28/parquet_cascading.md#L115
but it's not enforced. I'm going to include this fix in
https://github.com/apache/parquet-mr/pull/189
> It should not be possible to project away columns of a key in a map in
> parquet-thrift
