Hello Frens, This is a duplicate note of the previous one I sent, since it deserves a separate thread :)
I have setup hadoop/nutch on two node cluster. But looking at hadoop admin client I only see one node live. I suspect that the slave is not communicating. On debugging the problem here is what i found out I have set the <name>mapred.job.tracker</name> value to <value>hostname:40070</value>. So , the slaves must communicate on 40070 On the Master Node the process that listens on 40071 looks like this. lsof -i -n -P | grep 400 java 10766 nutch 34u IPv6 1460375 TCP 127.0.0.1:40070 (LISTEN) java 10766 nutch 38u IPv6 1462135 TCP 127.0.0.1:40070->127.0.0.1:60165(ESTABLISHED) 127.0.0.1:40070 means the java process on 40070 can only listen to localhost, therefore all slave connections will be rejected. What am I missing here ?
