Andras Bokor commented on HADOOP-8030:
--------------------------------------
I agree. Quiet mode not just hide some logs but works differently.
> Configuration class can throw exceptions in quiet mode; quiet mode usage
> unclear

> Key: HADOOP-8030
> URL: https://issues.apache.org/jira/browse/HADOOP-8030
> Project: Hadoop Common
> Issue Type: Bug
> Components: conf
> Reporter: Elias Ross
>
> hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/conf/Configuration.java
> if (doc == null && root == null) {
> if (quiet)
> return;
> throw new RuntimeException(name + " not found");
> }
> Unclear why a diagnostic mode would throw an exception, while normally off it
> would not.
> It's also not clear why 'quiet' is being passed around as well. Why not use
> logging levels and logging configuration and remove 'quiet' mode altogether?
