----------------------------------
I find parquet log is still noisy log output. eg:

> Turn off noisy log output produced by Parquet 1.7.0
> ---------------------------------------------------
>
> Key: SPARK-8118
> URL: https://issues.apache.org/jira/browse/SPARK-8118
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 1.4.1, 1.5.0
> Reporter: Cheng Lian
> Assignee: Cheng Lian
> Priority: Minor
> Fix For: 1.5.0
>
>
> 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.
