Allen Wittenauer resolved HADOOP-5069. -------------------------------------- Resolution: Fixed We replaced ant with maven. Closing as fixed. > add a Hadoop-centric junit test result listener > ----------------------------------------------- > > Key: HADOOP-5069 > URL: https://issues.apache.org/jira/browse/HADOOP-5069 > Project: Hadoop Common > Issue Type: New Feature > Components: test > Affects Versions: 0.21.0 > Reporter: Steve Loughran > Priority: Minor > > People are encountering different problems with hadoop's unit tests, defects > currently being WONTFIX'd > # HADOOP-5001 : Junit tests that time out don't write any test progress > related logs > # HADOOP-4721 : OOM in .TestSetupAndCleanupFailure > There is a root cause here, the XmlResultFormatter of Ant buffers everything > before writing out a DOM. Too much logged: OOM and no output. Timeout: kill > and no output. > We could add a new logger class to hadoop and then push it back into Ant once > we were happy, or keep it separate if we had specific dependencies (like on > hadoop-dfs API) that they lacked. > Some ideas > # stream XML to disk. We would have to put the test summary at the end; could > use XSL to generate HTML and the classic XML content > # stream XHTML to disk. Makes it readable as you go along; makes the XSL work > afterwards harder. > # push out results as records to a DFS. There's a problem here in that this > needs to be a different DFS from that you are testing, yet it needs to be > compatible with the client. > Item #3 would be interesting but doing it inside JUnit is too dangerous > classpath and config wise. Better to have Ant do the copy afterwards. What is > needed then is a way to easily append different tests to the same DFS file in > a way that tools can analyse them all afterwards. The copy is easy -add a new > Ant resource for that- but the choice of format is trickier. > Here's some work I did on this a couple of years back; I've not done much > since then: > http://people.apache.org/~stevel/slides/distributed_testing_with_smartfrog_slides.pdf > Is anyone else interested in exploring this? -- This message was sent by Atlassian JIRA (v6.2#6252)
