Akira Ajisaka commented on HADOOP-14587:
----------------------------------------
bq. I found org.slf4j.LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME) is not
equivalent to org.apache.log4j.Logger.getRootLogger().
You are right. If there is a logger named "ROOT", LoggerFactory.getLogger gets
the logger instead of root logger. I'm +1 for creating a helper method in
GenericTestUtils and avoid using {{org.slf4j.LoggerFactory.getLogger("org")}}
as workaround.
> Use GenericTestUtils.setLogLevel when available in hadoop-common

> Based on Brahma's comment in HADOOP-14296, it's better to use
> GenericTestUtils.setLogLevel as possible to make the migration easier.
> Based on Akira Ajisaka's comment in HADOOP-14549, create a separate jira for
> hadoop-common change.
