Subject [jira] [Commented] (HADOOP-13344) Add option to exclude Hadoop's SLF4J binding
Date Tue, 12 Jul 2016 18:25:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13344?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15373399#comment-15373399

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

I don't think we would want (or need to) change dependency information for anything but common,
because that's the classpath most often used by other applications. I'm taking a deeper look
into it. It may be that the best solution is to remove the slf4j binding from every classpath,
and I agree, that would be a big change.

> 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.
