Karthik Kambatla commented on YARN-1383:
----------------------------------------

Spoke to Sandy offline. 

It should be okay to leave the following debug message and remove the node updates:
{code}
    if (LOG.isDebugEnabled()) {
      LOG.debug("nodeUpdate: " + nm + " cluster capacity: " + clusterCapacity);
    }
{code}

> Writing out a line whenever a node heartbeats is not useful and just too much.
