Description

As described here:

http://mail-archives.apache.org/mod_mbox/mahout-user/201106.mbox/[e-mail]%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]));
