Subject [jira] Commented: (MAPREDUCE-1155) Streaming tests swallow exceptions
Date Wed, 30 Dec 2009 19:50:29 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12795413#action_12795413
] 

Kay Kay commented on MAPREDUCE-1155:
------------------------------------

Quick look at a test case(  TestStreamingExitStatus )  means it is doing the cleanup in the
setUp() method to make sure things are ok ( like deleting directories etc.) . 

There is a missing tearDown() method that needs to handle the unwinding of the changes, and
setUp() would probably just assert its assumptions before starting afresh. 

Also this patch seems to address more than one issue at hand. 

If this makes the build green - can we place have it committed on the trunk now and revisit
piecemeal, since the trunk build has been broken for quite some time.

> Many of the streaming tests (including TestMultipleArchiveFiles) catch exceptions and
print their stack trace rather than failing the job. This means that tests do not fail even
when the job fails.
