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

I believe PARQUET-369 is the root cause of this issue, and unfortunately I 
couldn't figure out a way that works all the time to fix the Parquet log 
redirection issue (even through hacky reflection tricks). The best way to fix 
this issue to stop shading slf4j in parquet-format.

> Turn off noisy log output produced by Parquet 1.7.0

> 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.
