Thanks @sebastian-nagel , I addressed the following two isses
* formatting in ivy.xml
* introduced logic for `org.apache.hadoop` classes to only log `WARN` and
worse... I agree with you this is much better.
Regarding your comments on HADOOP-12956, I also note following entries in
STDOUT
```
log4j:WARN No appenders could be found for logger
(org.apache.htrace.core.Tracer).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for
more info.
```
Does HADOOP-12956 stop us from implementing this and then revisiting it once
HADOOP-12956 has been included in a forthcoming Hadoop release?
