[jira] [Created] (YARN-2875) Bump SLF4J to 1.7.7 from 1.7.5
Tim Robertson created YARN-2875:
-----------------------------------
Summary: Bump SLF4J to 1.7.7 from 1.7.5
Key: YARN-2875
URL: https://issues.apache.org/jira/browse/YARN-2875
Project: Hadoop YARN
Issue Type: Bug
Reporter: Tim Robertson
Priority: Minor
hadoop-yarn-common [uses log4j directly|https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/pom.xml#L167] and when trying to redirect that through an SLF4J bridge version 1.7.5 has issues, due to use of methods missing in log4j-over-slf4j version 1.7.5.
This is documented on the [1.7.6 release notes|http://www.slf4j.org/news.html] but 1.7.7 should be suitable.
This is applicable to all the projects using Hadoop motherpom, but Yarn appears to be bringing Log4J in, rather than coding to the SLF4J API.
The issue shows in the logs as follows in Yarn MR apps, which is painful to diagnose.
