["Amareshwari Sriramadasu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LENS-666?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14655050#comment-14655050 ] 

Amareshwari Sriramadasu commented on LENS-666:
----------------------------------------------

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.
{noformat}

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?
