Right now presto does not support reading TIMESTAMP_MICROS type. This needs to be fixed from the presto side for which I am working on a fix. ( presto only supports timestamp upto millisecond granularity so the fix will simply convert the microsecond to millisecond ) I think `spark.sql.parquet.outputTimestampType` is not working because hudi is using spark's [SchemaConvertors](https://github.com/apache/spark/blob/master/external/avro/src/main/scala/org/apache/spark/sql/avro/SchemaConverters.scala#L150) which is not even looking at this option. This might be because that property was to control the parquet type but hudi uses avro format to store the schema of the file within parquet. It would be very difficult to change this from the hudi or spark side. Right now the easiest option is to choose the double type as mentioned above till the fix merges to presto. I will share the PR link here in couple days ( I need to refactor it since the presto version is custom internal version ) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
