Hama Example Running Problems
Hii,
I am having an installation of hadoop working perfectly fine. Then I
installed hama and tried to run an example but it gives the following
error. I was able to run this example perfectly well a few days back on my
computer.
It just hangs when I run the example. The logs continue to be generated
even when I ctrl+C. It is only after I shut down hama that logs are
terminated.
I have checked all confs are fine.
Somehow the connection is failing. The hadoop.tmp.dir = /app/hadoop-0.20/tmp
fs.default.name =
hdfs://localhost:9000/
The folder /app/hadoop-0.20/tmp is accessible by the user running the hama
and hadoop.
The namenode is on as do the jps and the web interface tells.

Hi,
Please use the version 0.20.2 of hadoop.
