Edward,
I traced the problem in the code to hama.groomserver.local.dir which is
undefined. So I searched for it and found
https://svn.apache.org/repos/asf/incubator/hama/trunk/src/java/groomserver-default.xml
which contains the following:
<property>
<name>hama.groomserver.local.dir</name>
<value>${hadoop.tmp.dir}/groomserver/local</value>
</property>
We debated about whether we simply needed this specific file
(groomserver-default.xml) but in the end just tucked this
property inside hama-default.xml and now the groomserver process shows up.

Subject: Re: Hama Groomserver error
Hi,
For the time being, you don't need to run that server to perform the
matrix M/R computations at this time. (It's a graph computing server,
and still working in progress)
However, I'll check that error.
Thanks!
