You will need spark to re-write this parquet with timestamp in INT64 TimestampType and then the json output will produce a timestamp (in the format you desire). avro. The same functionality has already been re-added into parquet-pig (PARQUET-1133). However, Apache Spark still uses INT96 as the default outputTimestampType for Parquet files (code link). 12.
