Subject [jira] Commented: (HDFS-451) Test DataTransferProtocol with fault injection
Date Fri, 07 Aug 2009 18:37:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12740672#action_12740672
] 

Tsz Wo (Nicholas), SZE commented on HDFS-451:
---------------------------------------------

The failed tests, TestBlockReplacement and TestNameNodeMetrics, are not related to this. 
This issue adds new fault inject tests but does not change existing codes except that the
patch adds a few getter methods.

Unfortunately, Hudson fails on testPipelineFi12.

Note that the fault inject tests do not show up in the [test result page|http://hudson.zones.apache.org/hudson/job/Hdfs-Patch-vesta.apache.org/47/testReport/]
although they have been executed.

tests.
