> -----------------------------------------------------------------------------
>
> Key: MAHOUT-408
> URL: https://issues.apache.org/jira/browse/MAHOUT-408
> Project: Mahout
> Issue Type: Bug
> Affects Versions: 0.4
> Reporter: Shannon Quinn
> Priority: Minor
> Fix For: 0.4
>
> Attachments: MAHOUT-408.patch
>
>
> The following Mahout programs incorrectly processed -h flags, throwing OptionExceptions:
> seq2sparse
> seqdirectory
> seqwiki
> svd
> trainclassifier
> transpose
> The first five are easily addressed by adding "parser.setHelpOption(helpOpt)" in the correct driver files (thanks to Jeff Eastman). The "transpose" program also contained a NullPointerException thrown when two integer arguments were not verified. See the patch file for a possible fix.
