Thomas Poepping commented on HADOOP-13344: ------------------------------------------ That was my mistake, I didn't mean to include 2.7.2 as a target version, only 2.8.0. I found while writing this that we could use 'jar tf ${jarname}', but that was always much slower than grepping the jarfile directly. As far as documentation, I don't have any plans. I assume that any documentation that already exists regarding hadoop-config.sh should have this feature documented. As far as client applications have documentation, I don't see any good way to do it. We can't very well change the documentation of each application depending on Hadoop. It could also be added to a hadoop-config help method, if one exists. I'll look into it. First and foremost though -- I'll be targeting trunk. The reason I targeted this directly is because the structure of the hadoop-config file is very different in trunk. > 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 > 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
