[jira] Commented: (HBASE-2608) Switch to SLF4J

["Lars Francke (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-2608?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12894647#action_12894647 ] 

Lars Francke commented on HBASE-2608:
-------------------------------------

I'll finish up my other small issues and then take a stab at this by converting the necessary config files and check out the web frontend.

When we have the config files in place everyone can transparently decide if he wants to use commons-logging API (which should ideally phased out) or SLF4j. It doesn't make a difference because the CL jar gets replaced by a wrapper that forwards all calls to SLF4J anyway. This should make it very easy for everyone to adapt if you decide to go this way.

> There are 2 compelling reasons to switch from log4j to slf4j:
> * HBase provides a client library that is going to be embedded in another application.  Using SLF4J lets the application chose whatever logging library it wants instead of imposing log4j.
> * When using SLF4J, we should use logback by default as it is basically a better, faster, stronger log4j.  Same author, new design / new code.  See http://logback.qos.ch/reasonsToSwitch.html
