> Twenty Newsgroups Classification Example fails in case running with
> {{MAHOUT_LOCAL=true}} 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.
