             Summary: RMContainerRequestor#makeRemoteRequest has confusing log message
                 Key: YARN-9355
                 URL: https://issues.apache.org/jira/browse/YARN-9355
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Szilard Nemeth


org.apache.hadoop.mapreduce.v2.app.rm.RMContainerRequestor#makeRemoteRequest has this log: 

{code:java}
if (ask.size() > 0 || release.size() > 0) {
      LOG.info("getResources() for " + applicationId + ":" + " ask="
          + ask.size() + " release= " + release.size() + " newContainers="
          + allocateResponse.getAllocatedContainers().size()
          + " finishedContainers=" + numCompletedContainers
          + " resourcelimit=" + availableResources + " knownNMs="
          + clusterNmCount);
    }
{code}
The reason why "getResources()" is printed because org.apache.hadoop.mapreduce.v2.app.rm.RMContainerAllocator#getResources invokes makeRemoteRequest. This is not too informative and error-prone as name of getResources could change over time and the log will be outdated. Moreover, it's not a good idea to print a method name from a method below the current one in the stack.
