    Description

      We saw an instance where this log message was generated millions of times in a short time interval, slowing the NameNode to a crawl. It can probably be changed to log at DEBUG level instead.

            if (cur == null) {
              LOG.warn("No excess replica can be found. excessTypes: "+excessTypes+
                  ". moreThanOne: "+moreThanOne+". exactlyOne: "+exactlyOne+".");
              break;
            }
