Hi *,
I was playing around with the latest hadoop (0.12.1) on a virtual
"cluster"
(4 nodes, one as namenode and jobtracker) using Xen. Each node runs the
current Xen kernel (2.6.16.33-xen) with 192 MB Ram and JDK 1.5.0_11.
Running the grep example in standalone mode works fine, but it won't
terminate in distributed mode:
Maybe 192MB of RAM for each nodes is not enough ?
~/hadoop$ ./bin/hadoop jar hadoop-0.12.1-examples.jar grep input output
'dfs[a-z.]+'

(... and goes on and on ...)
Is there something wrong with my setup?
Thanks,
