Subject [jira] [Commented] (HADOOP-13344) Add option to exclude Hadoop's SLF4J binding
Date Fri, 12 Aug 2016 20:36:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13344?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15419433#comment-15419433
] 

Thomas Poepping commented on HADOOP-13344:
------------------------------------------

I would say we can't unconditionally remove the binding, because hadoop code itself will still
need an slf4j binding to accurately log items it tries to log. I'll work to getting my updated
patch posted here

> If another application that uses the Hadoop classpath brings in its own SLF4J binding
for logging, and that jar is not the exact same as the one brought in by Hadoop, then there
will be a conflict between logging jars between the two classpaths. This patch introduces
an optional setting to remove Hadoop's SLF4J binding from the classpath, to get rid of this
problem.
> This patch should be applied to 2.8.0, as bin/ and hadoop-config.sh structure has been
changed in 3.0.0.
