[jira] Commented: (MAHOUT-294) Uniform API behavior for Jobs
[ https://issues.apache.org/jira/browse/MAHOUT-294?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12868734#action_12868734 ]
Jeff Eastman commented on MAHOUT-294:
-------------------------------------
I've cleaned up the clustering driver command processing by refactoring all of the options into the DefaultOptionCreator and standardizing option names, descriptionsw, required/optional and default values. I also updated all of the clustering .props files for MAHOUT-301 to include sections on required and optional parameters and default values. All .props files contain comments that can be activated by users editing the files.
> Uniform API behavior for Jobs
> -----------------------------
>
> Key: MAHOUT-294
> URL: https://issues.apache.org/jira/browse/MAHOUT-294
> Project: Mahout
> Issue Type: Improvement
> Components: Classification, Clustering, Collaborative Filtering, Frequent Itemset/Association Rule Mining, Genetic Algorithms, Math, Utils
> Affects Versions: 0.4
> Reporter: Robin Anil
> Fix For: 0.4
>
>
> * Move AbstractJob to common and convert all the Driver classes to extend that.
> One suggestion is:
> AlgorithmParams params = ParamsBuilder.build().withParam("-i", input).withParam("-o", output)....
> MyAlgorithmn.runJob(params) throws ParameterMissingException;
> * Give uniform command-line parameters for various algorithms.
> e.g Currently distance measure is -d, -dm, -m at different places in clustering
> * Add a temp directory as a parameter http://www.lucidimagination.com/search/document/28a979aa62c02a1/who_owns_mahout_bucket_on_s3#ddb5855e8bdace45
> This issue will keep track of all discussion/patches related to the design and cleanup of Mahout API
