Steve Loughran commented on HADOOP-4901: ---------------------------------------- a lot of the tests are a bit weak on releasing the miniMR clusters on failure. As long as everything works, nobody notices, but when a test fails, the clusters hang around. It's that cluster setup/teardown that causes a lot of the tests to be slow -if teardown could be asynchronous, maybe even with queued creation of MiniMRClusters, things could be faster. > Upgrade to JUnit 4 > ------------------ > > Key: HADOOP-4901 > URL: https://issues.apache.org/jira/browse/HADOOP-4901 > Project: Hadoop Core > Issue Type: Improvement > Components: test > Reporter: Tom White > Assignee: Alex Loddengaard > > Amongst other things, JUnit 4 has better support for class-wide set up and > tear down (via @BeforeClass and @AfterClass annotations), and more flexible > assertions (http://junit.sourceforge.net/doc/ReleaseNotes4.4.html). It would > be nice to be able to take advantage of these features in tests we write. > JUnit 4 can run tests written for JUnit 3.8.1 without any changes. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
