Summary: Avro maps drop null values
Key: PARQUET-192
URL: https://issues.apache.org/jira/browse/PARQUET-192
Project: Parquet
Issue Type: Improvement

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.
