Description

Currently adjusting logging configuration for Catalog and impalads require a restart of services. It is a big supportability pain in production environments. A nice feature for supportability purposes is to have dynamic log4j configuration which doesn't require a restart of daemons. This jira aims to have a easy way to change logging level per class/per package without service restarts.
