Sean Owen resolved MAHOUT-580.
------------------------------
Resolution: Fixed
> Missing basePath in Bayes job / InMemoryDataStore
> -------------------------------------------------
>
> Key: MAHOUT-580
> URL: https://issues.apache.org/jira/browse/MAHOUT-580
> Project: Mahout
> Issue Type: Bug
> Components: Classification
> Affects Versions: 0.4
> Reporter: Sean Owen
> Assignee: Robin Anil
> Fix For: 0.5
>
> Attachments: MAHOUT-580.patch
>
>
> Reported on user@ by Pierre Mage:
> I found the following issue in the trunk: If the dataSource option is "hdfs"
> in org.apache.mahout.classifier.
> Classify, there is a problem with InMemoryBayesDatastore because its
> basePath param is not defined :
> To fix it, I edited Classify like this:
> 122. if ("hdfs".equals(dataSource)) {
> 123. params.set("basePath", modelBasePath);
> Yes, looks like InMemoryDataStore expects this to be set -- so does
> HBaseDataStore. But that takes the base path (table) separately as a param.
> And InMemoryDataStore doesn't take it at all. I adjusted this since it seems
> correct. And then tried to centralized handling of Bayes params in
> BayesParameters since it seems to get half processed in this class only.
> I have attached my own rather more elaborate patch that reflects this.
