Sean Owen updated MAHOUT-799:
-----------------------------
Attachment: MAHOUT-799.patch
Hmm, the author didn't follow up. As far as I can tell, the -filter option
should never have been added. The only subclass was not written to work as an
'argument', but only as a command-line program. My best fix is to just remove
it. You can use this, still, by running it directly as the command-line program.

> Components: Examples
> Affects Versions: 0.5
> Reporter: Jack Tanner
> Assignee: Sean Owen

> As described here:
> http://mail-archives.apache.org/mod_mbox/mahout-user/201106.mbox/%[email protected]%3E
> SequenceFilesFromCsvFilter cannot be invoked with default parameter values,
> because it dies like so:
> bin/mahout seqdirectory -i input -o output -filter
> org.apache.mahout.text.SequenceFilesFromCsvFilter
> ...
> Caused by: java.lang.NumberFormatException: null
> at java.lang.Integer.parseInt(Integer.java:417)
> at java.lang.Integer.parseInt(Integer.java:499)
> at
> org.apache.mahout.text.SequenceFilesFromCsvFilter.<init>(SequenceFilesFromCsvFilter.java:56)
> If one adds the parameters -kcol 0 -vcol 0 (or their long-form versions), it
> dies like so:
> Unexpected -kcol while processing Job-Specific Options
> Commenting out SequenceFilesFromCsvFilter:56 and
> SequenceFilesFromCsvFilter:57, like so, allows the run to proceed
> // this.keyColumn = Integer.parseInt(options.get(KEY_COLUMN_OPTION[0]));
> // this.valueColumn =
> Integer.parseInt(options.get(VALUE_COLUMN_OPTION[0]));
