------------------------------------
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getResources could change over time and the log will be outdated.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.
