[jira] [Created] (PARQUET-192) Avro maps drop null values

Ryan Blue created PARQUET-192:
---------------------------------

             Summary: Avro maps drop null values
                 Key: PARQUET-192
                 URL: https://issues.apache.org/jira/browse/PARQUET-192
             Project: Parquet
          Issue Type: Improvement
          Components: quet-mr, parquet-mr
            Reporter: Ryan Blue


The Avro serialization code for maps writes all keys and then all values without calling start and end to detect and handle null values. This causes the code to drop null values.
