Subject [jira] Commented: (HADOOP-6003) AspectJ framework for HDFS code and tests
Date Mon, 15 Jun 2009 03:54:07 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6003?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12719382#action_12719382

Philip Zeyliger commented on HADOOP-6003:

It looks like some of the patches have inconsistent usage of tabs/spaces; you may want to
clean that up.

bq. It is expected to see unit tests failing with faults in place. We might need to develop
different kind of tests to utilize fault injection in a better way.

I think you're right on here.  It seems like having a global setting for injection probability
will mostly lead to test results that are hard to grok.  Have you thought about setting up
a separate package/target for tests that are designed to interact with injected faults?  Once
one or two of those tests exists, it'll be clearer whether "ant run-test-hdfs -Dfault.probability.FSDataset=3"
is the right API.
