Suneel Marthi commented on MAHOUT-1864:
---------------------------------------

I would vote to resolve this jira as 'Won't Fix' .  We have ceased support for this since
0.9 release.

or else when {{HADOOP_HOME}} env variable is not set.
> [Newsgroups|https://mahout.apache.org/users/classification/twenty-newsgroups.html] lists
instructions in order to run this classifier. When running in standalone mode({{MAHOUT_LOCAL=true}}),
i.e., running {{$ ./examples/bin/classify-20newsgroups.sh}}, the script runs {{./examples/bin/set-dfs-commands.sh}}
internally to export hadoop related env variables.
> {{set-dfs-commands.sh}} attempts to check for hadoop version despite running with {{MAHOUT_LOCAL}}
set as true. IMHO, the script works fine considering the prerequisites, but, it will as well
make sense if we can update the script {{./examples/bin/set-dfs-commands.sh}} to export hadoop
env varibales only in case {{MAHOUT_LOCAL}} is not set to true.
