Gabor Szadovszky commented on PARQUET-2103:
-------------------------------------------
I think, we need to update
[ParquetMetadata.toJSON|https://github.com/apache/parquet-mr/blob/master/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/metadata/ParquetMetadata.java#L67-L71].
Jackson shall be able to be configured to not to look for getter methods but
the private fields. I am not sure if it is a good idea or if it will work in
every environment. Another option would be to refactor
EncryptedColumnChunkMetaData to not to call "decrypt" for a getter but it might
not worth the efforts. The easiest way would be to simply detect if the
metadata contains encrypted data and do not log anything. I don't know how
urgent might it be to log the metadata in case of debugging.
