Mahout CLI OptionExceptions when given "-h" or "--help" for specific programs
-----------------------------------------------------------------------------
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
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.
