consider logical type
john lilley created PARQUET-1943:
------------------------------------
Summary: parquet-tools cat command does not consider logical type
Key: PARQUET-1943
URL: https://issues.apache.org/jira/browse/PARQUET-1943
Project: Parquet
Issue Type: Bug
Components: parquet-mr
Affects Versions: 1.11.1
Reporter: john lilley
Attachments: datetime_utc_adjust.parquet
The parquet-tools cat command doesn't format timestamps, outputting them as numbers instead. The parquet-tools dump command does format as timestamps, so the code has been written.
Using the attached file:
$ java -jar parquet-tools-<VERSION>.jar cat -j datetime_utc_adjust.parquet
{"ID":1,"DT":1604297946277}
$ java -jar parquet-tools-<VERSION>.jar dump datetime_utc_adjust.parquet
