title: Could the slave node run Hadoop Map/Reduce Job?
body: <p>I installed Hadoop on two nodes ( Master and Slave nodes). I would ask if i can run Map/Reduce job from the Slave Machine or use the HDFS from the Slave machine. There is no problem by running the map/reduce job from Master Node, but when I tried to run the Map/Reduce Job from Slave node, the following Error showed up.</p>
  
  <p>Java.net.connectionException failed on connection exception.</p>
