Subject [jira] Commented: (MAPREDUCE-1654) Automate the job killing system test case.
Date Mon, 12 Apr 2010 11:00:50 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1654?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12855922#action_12855922

Iyappan Srinivasan commented on MAPREDUCE-1654:

Hi Balaji,

Patch looks good.

Some coments:

1) The LogFactory.getLog(TestCluster.class) should point to the correct class.

2) The name of the "before" and "after" methods can be more meaningful like "setup" and "cleanup"

3) All Assert statements should have comments, so taht it gives out a meaningful statement
when taht failure hapens.

4) Both BeforeClass method and AfterClass method should delete both the input Directoy and
output Directory. Reason being for BeforeClass, some other testcase might have already created
this directory, so when this testcase starts, it should delete it, if it exists, as a precaution.
Reason for afterClass is the testcase might fail at any point in the testExecution, so when
it exits, even in failure, it should delete those directories and then exit.

5) Comment explaing the TestJobKill.java funtionality can be  little more clear "The test
checks after job failure that a file called "success" 
 does not exist in the output directory"

6) Comment explaining the "JobKillCommitter". Some of htem are like "The class is used provides".
IT can be changed to "This class provides"
