Akira Ajisaka commented on HADOOP-14549:
----------------------------------------
Thanks [~vincent he] for taking this issue!
bq. Which one do you intend to do? Replacing all
org.apache.log4j.Logger.setLevel where GenericTestUtils.setLogLevel available
in WHOLE hadoop project or in some certain module like hadoop-tool?
Replacing in whole hadoop project seems big change, I prefer doing it by
package/module
bq. GenericTestUtils.setLogLevel is still using org.apache.log4j.Level as
parameter which is log4j1 api. In log4j2, this changed to
org.apache.logging.log4j.Level. Is this OK for us to migration to log4j2?
This is okay. When migrating to log4j2, we need to update GenericTestUtils and
that's all. If we don't do this, we need to update all the usage of
{{org.apache.log4j.Logger.setLoglevel}} when upgrading to log4j2.
> Use GenericTestUtils.setLogLevel when available

> in HADOOP-14296, it's better to use GenericTestUtils.setLogLevel as possible
> to make the migration easier.
