> Too many INFO log messages written out during AM to RM heartbeat. Based on default frequency of 1000ms (scheduler.heartbeat.interval-ms) either 2 or 4 INFO messages are written out per second:
> LOG.info("Before Scheduling: " + getStat());
> List<Container> allocatedContainers = getResources();
> LOG.info("After Scheduling: " + getStat());
> if (allocatedContainers.size() > 0) {
> LOG.info("Before Assign: " + getStat());
> scheduledRequests.assign(allocatedContainers);
> LOG.info("After Assign: " + getStat());
> }
> These should probably be changed to DEBUG message to save the log growing too quickly.
