AvroParquetWriter and local timestamp problems

[Stefan Ziegler <st...@gmail.com>]

Hi

I'm trying to create some parquet files with the AvroParquetWriter but I'm
struggling with timestamps. It seems that avro supports timetamps without
time zone (aka isAdjustedToUTC=false) and I can create a field with the
according logical type: "LocalTimestampMillis datetimeType =
LogicalTypes.localTimestampMillis();"

But every client I use just interprets the field as bigint or int64. As far
as I understand the AvroSchemaConverter code, the conversion of the "local
timestamp" is missing:
https://github.com/apache/parquet-mr/blob/master/parquet-avro/src/main/java/org/apache/parquet/avro/AvroSchemaConverter.java#L445

Not sure if this is true and if it would need some adjustments in other
areas.

best regards
Stefan
