[jira] [Commented] (LENS-171) Porting System.out and System.err to Slf4j log statements

["Rajat Khandelwal (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LENS-171?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14270857#comment-14270857 ] 

Rajat Khandelwal commented on LENS-171:
---------------------------------------

I don't think it matters for test cases and example code. But for all other (*/src/main) we should move away from System.out/err

> There are 266 occurences of System.out (Pasted below) and 7 occurences of System.err in Lens code. Suggestion is to port them to Slf4j log statements which can be controlled efficiently through logging configuration files.
