Subject [jira] [Commented] (MAPREDUCE-3087) CLASSPATH not the same after MAPREDUCE-2880
Date Fri, 21 Oct 2011 15:44:32 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3087?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13132758#comment-13132758
] 

Ravi Prakash commented on MAPREDUCE-3087:
-----------------------------------------

Vinod! Thanks for your comment. The contents of the mrapp-generated-classpath in the test-mr-app.jar
file I uploaded are :

{noformat}
$ cat mrapp-generated-classpath
/somePath1/someJar1.jar:/somePath2/someJar2.jar:/somePath3/someJar3.jar
{noformat}

It does not need to be automatically generated. It is present ONLY because setMRFrameworkClasspath
looks for mrapp-generated-classpath on MRApps.java:181
bq. classpathFileStream = thisClassLoader.getResourceAsStream(mrAppGeneratedClasspathFile);

Without it, my test would throw an exception because the call above would return null. The
specific line I want to exercise (MRApps.java:192) in the unit test comes after this line.


If you have another way to structure the test, please suggest it.

OR we can check in the single line change (MRApps.java:192) which we all agree is right without
writing this test.
