yes of course. I attached 2 files. the proto file is :

message Log
{ 
    optional string date = 1; 
    optional string url = 2; 
}

in the files,one sample record is written repeatedly. File url_column_completely_null.parquet, as the name suggests have a complete null column. File url_column_onetime_value.parquet, in just one record, has value for 'url' column. The latter can be queried by drill while the former throws a null pointer exception
