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.
