MAHOUT-1864: Twenty Newsgroups Classification Example fails in case running
with MAHOUT_LOCAL=true
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.
