Description

hadoop-yarn-common uses log4j directly and when trying to redirect that through an SLF4J bridge version 1.7.5 has issues, due to use of AppenderSkeleton which is missing in log4j-over-slf4j version 1.7.5.

This is documented on the 1.7.6 release notes 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.
