[jira] [Commented] (SPARK-12347) Write script to run all MLlib examples for testing

["Jun Zheng (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-12347?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15080564#comment-15080564 ] 

Jun Zheng commented on SPARK-12347:
-----------------------------------

1. How to programmatically detect if a test requires input? I can see a ".required()" keyword in OptionParser indicates the test needs input, but not all test that needs input have this keyword.

2. How to set input file names other than hard-coding?

> It would facilitate testing to have a script which runs all MLlib examples for all languages.
> Design sketch to ensure all examples are run:
> * Generate a list of examples to run programmatically (not from a fixed list).
> * Use a list of special examples to handle examples which require command line arguments.
> * Make sure data, etc. used are small to keep the tests quick.
> This could be broken into subtasks for each language, though it would be nice to provide a single script.
> Not sure where the script should live; perhaps in {{bin/}}?
