Subject [jira] [Commented] (HADOOP-11929) add test-patch plugin points for customizing build layout
Date Fri, 29 May 2015 15:09:18 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11929?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14564937#comment-14564937
] 

Allen Wittenauer commented on HADOOP-11929:
-------------------------------------------

OK, that bad run did highlight some things:

* bzip2 is broken on the jenkins servers too.  So this might not just be an OS X problem.
* javadoc output needs to be cleanedup
* better hit checkstyle sooner rather than later
* newer routines aren't using @@BASEDIR@@
* I don't like the / separator.
* Still some bugs in the clock. No way @author took 5 minutes and the framework took 80. lol

> Sean Busbey and I had a chat about this at the Bug Bash. Here's the proposal:
>   * Introduce the concept of a 'personality module'.
>   * There can be only one personality.
>   * Personalities provide a single function that takes as input the name of the test
current being processed
>   * This function uses two other built-in functions to define two queues: maven module
name and profiles to use against those maven module names
>   * If something needs to be compiled prior to this test (but not actually tested), the
personality will be responsible for doing that compilation
> In hadoop, the classic example is hadoop-hdfs needs common compiled with the native bits.
So prior to the javac tests, the personality would check CHANGED_MODULES, see hadoop-hdfs,
and compile common w/ -Pnative prior to letting test-patch.sh do the work in hadoop-hdfs.
Another example is our lack of test coverage of various native bits. Since these require profiles
to be defined prior to compilation, the personality could see that something touches native
code, set the appropriate profile, and let test-patch.sh be on its way.
> One way to think of it is some higher order logic on top of the automated 'figure out
what modules and what tests to run' functions.
