> 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 name of getResources could change over time and the log will be outdated.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.
