Cheng Lian commented on SPARK-8118:
-----------------------------------

Yea, unfortunately at last we found that due to a few Parquet side bugs, it is 
pretty hard to override Parquet logging in user applications. See PARQUET-401. 
This will probably be fixed in a clean way once we upgrade to parquet-mr 1.9 
(which hasn't been released yet).

> Parquet 1.7.0 renames package name to "org.apache.parquet", need to adjust 
> {{ParquetRelation.enableLogForwarding}} accordingly to avoid noisy log output.
> A better approach than simply muting these log lines is to redirect Parquet 
> logs via SLF4J, so that we can handle them consistently. In general these 
> logs are very useful. Esp. when used to diagnosing Parquet memory issue and 
> filter push-down.
