-------------------------------------------

             Summary: ContainersMonitorImpl logged message lacks detail when exceeding memory
limits
                 Key: YARN-7580
                 URL: https://issues.apache.org/jira/browse/YARN-7580
             Project: Hadoop YARN

Currently in the RM logs container memory usage for a container that exceeds the memory limit
is reported like this:

2016-06-14 09:15:36,694 INFO [AsyncDispatcher event handler] org.apache.hadoop.mapreduce.v2.app.job.impl.TaskAttemptImpl:
Diagnostics report from attempt_1464251583966_0932_r_000876_0: Container [pid=134938,containerID=container_1464251583966_0932_01_002237]
is running beyond physical memory limits. Current usage: 1.0 GB of 1 GB physical memory used;
1.9 GB of 2.1 GB virtual memory used. Killing container.
