Is there any way for the master to know about how much message traffic is

The most simple solution is to use an aggregator.

Hey Andro,
I believe the reason you are seeing this error is due to ports being
blocked by iptables. You need to have port 3 open for the master on all
machines in your cluster. You also need to open ports 30001 up to the
number of workers you will be running.
So if you are running 10 workers
Yes, that would be the reason. In addition to the ports for netty, you also
need to accept connections to Zookeeper (e.g. 22181).

I am unable to run giraph job successfully. My question is more generic:
1. How should one choose right amount of heap space? .. is there a way of

Are you sure the iptables rules were applied to all your servers? If you
run the command
sudo iptables -L
does it show the ports as open?

I added this two lines:

this is the output of the command in all servers:

You should try to utilize maximum of your RAM to map tasks. You can do that
by changing the parameters at mapred-site.xml file. add the below
statements to set 6.5 GB of RAM for map tasks
