----------------------------------------------
The review request for moving to logback is put up at
https://reviews.apache.org/r/36981/.
I'm facing couple of issues as mentioned on the review request, and not able to
proceed much with them.
# All the logs that are coming from dependent libraries (like hive, hadoop) are
landing in lensserver.out file (i.e. console), as they are not coming from
slf4j.
# Seeing the following while launching lens-cli.sh
{noformat}
log4j:WARN No appenders could be found for logger
(org.springframework.core.env.StandardEnvironment).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more
info.

Here is how lib/ folder on client looks :
client$ ls lib/*log*
lib/commons-logging-1.1.3.jar lib/log4j-1.2.17.jar
lib/logback-classic-1.1.3.jar lib/logback-core-1.1.3.jar
client $ ls lib/*slf*
lib/slf4j-api-1.7.6.jar
Anyone has ideas on what we can do with above?
