             Summary: Apache Pig cannot store Map data type into Parquet format
                 Key: PARQUET-402
                 URL: https://issues.apache.org/jira/browse/PARQUET-402
             Project: Parquet
          Issue Type: Bug
            Reporter: Jerry Ylilammi


Trying to store simple map with two entries gives me following exception:
{code}table_with_map_data: {my_map: map[]}
2015-12-10 11:58:54,478 [main] INFO  org.apache.hadoop.conf.Configuration.deprecation - fs.default.name is deprecated. Instead, use fs.defaultFS
2015-12-10 11:58:54,498 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2999: Unexpected internal error. Invalid map Schema, schema should contain exactly one field: my_map: map{code}

For example taking any input and doing this gives me the exception:
{code}table_with_map_data = FOREACH random_data GENERATE TOMAP('123', 'hello', '456', 'world') as (my_map);
DESCRIBE table_with_map_data;
STORE table_with_map_data INTO '...' USING ParquetStorer();{code}

I'm using latest version of Pig: Apache Pig version 0.15.0 (r1682971) compiled Jun 01 2015, 11:44:35
and Parquet: parquet-pig-bundle-1.6.0.jar
