Subject Hama Example Running Problems
Date Wed, 25 Jan 2012 02:20:02 GMT
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.
