May be you can try commenting the following 4 lines from the below mentioned script on all your cluster nodes. Followed by "metrics-monitor" restart on all the cluster nodes.

# grep -iR 'disk_io_counters' /usr/lib/python2.6/site-packages/resource_monitoring/core/metric_collector.py
      metrics.update(self.host_info.get_combined_disk_io_counters())
      metrics.update(self.host_info.get_disk_io_counters_per_disk())
      metrics.update(self.host_info.get_combined_disk_io_counters())
      metrics.update(self.host_info.get_disk_io_counters_per_disk())

After commenting / removing those lines you will need to restart the metrics monitor from ambari UI on all hosts (or better restart AMS service)
