Subject [jira] Commented: (PIG-55) Allow user control over split creation
Date Tue, 01 Apr 2008 18:34:24 GMT

    [ https://issues.apache.org/jira/browse/PIG-55?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12584242#action_12584242

Charlie Groves commented on PIG-55:
-----------------------------------

Ahh, I didn't realize it was failing from ant for you as well.  Ant didn't get support for
JUnit 4 tests until 1.7, so if you're running an earlier version, its runner won't pick them
up.  I assumed JUnit 4 style tests were acceptable for pig since several tests are using the
@Test, @Before and @After annotations, but it looks all of those tests are also using the
JUnit 3 style TestCase extension and method naming conventions.  If we don't want to require
Ant 1.7, I'm fine with converting the test to be JUnit 3 style.  However, if we're going to
do that, I'd like to fix the existing tests so they don't use both JUnit 3 and 4 styles.

> I have a dataset in HDFS that's stored in a file per column that I'd like to access from
pig.  This means I can't use LoadFunc to get at the data as it only allows the loader access
to a single input stream at a time.  To handle this usage, I've broken the existing split
creation code out into a few classes and interfaces, and allowed user specified load functions
to be used in place of the existing code.
