Hi,
I have a problem configuring Hadoop Map/Reduce plugin with Eclipse.
Setup Details:
I have a namenode, a jobtracker and two data nodes, all running on ubuntu.
My set up works fine with example programs. I want to connect to this setup
from eclipse.
namenode - 10.20.104.62 - 54310(port)
jobtracker - 10.20.104.53 - 54311(port)
I run eclipse on a different windows m/c. I want to configure map/reduce
plugin
with eclipse, so that I can access HDFS from windows.
Map/Reduce master
Host - With jobtracker IP, it did not work
Port - With jobtracker port, it did not work
DFS master
Host - With namenode IP, It did not work
Port - With namenode port, it did not work
I tried other combination too by giving namenode details for Map/Reduce
master
and jobtracker details for DFS master. It did not work either.
1. check the ports really are open by doing a netstat -a -p on the
namenode and job tracker ,
netstat -a -p | grep 54310 on the NN
netstat -a -p | grep 54311 on the JT
2l Then, from the windows machine, see if you can connect to them
oustide ecipse
telnet 10.20.104.62 54310
telnet 10.20.104.53 - 54311
If you can't connect, then firewalls are interfering
If everything works, the problem is in the eclipse plugin (which I don't
use, and cannot assist with)
