Sean Busbey commented on HADOOP-13344: -------------------------------------- For trunk, are we better off just unconditionally removing the binding? Presuming [~aw] still feels this way: {quote} * I think moving it to a place that may be optionally triggered off is a really the only realistic fix here. Munging the classpath to remove it (especially when we tend to use wildcards to speed things up), is just painful. * Since that path is default on, this shouldn't be an incompatible break. Users who turn it off are making the decision to disable it the same way they would a plug-in. This is nearly the same sorts of decisions we give users to turn things on, such as special options to fsck. {quote} then sure, I'd be fine with the pom fixes as a follow-up so long as the solution here doesn't obviously rely on something that would change as a result. If we're going to unconditionally remove the binding then I'd consider the maven fixes blocking, wether they happen here or in a different JIRA. > Add option to exclude Hadoop's SLF4J binding > -------------------------------------------- > > Key: HADOOP-13344 > URL: https://issues.apache.org/jira/browse/HADOOP-13344 > Project: Hadoop Common > Issue Type: New Feature > Components: bin, scripts > Affects Versions: 2.8.0, 2.7.2 > Reporter: Thomas Poepping > Assignee: Thomas Poepping > Labels: patch > Attachments: HADOOP-13344.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
