I have also noticed another issue when starting hadoop cluster start-all.sh 
command

namenode and datanode daemons are starting.But sometimes one of the datanode 
would drop the connection and it shows the message connection closed by 
((192.168.2.x -datanode)) everytime when it restart the hadoop cluster datanode 
will keeps changing .

for example 1st time when i starts hadoop cluster - 192.168.2.1 - connection 
closed
2nd time when i starts hadoop cluster - 192.168.2.2-connection closed .This 
point again 192.168.2.1 will starts successfuly without any errors.

I couldn't able to figure out the issue exactly.Is issue relates to network or 
Hadoop configuration.
