---------------------------------------
Summary: TestMRAppComponentDependencies causes surefire to exit
without saying proper goodbye
Key: MAPREDUCE-5714
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5714
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: test
Affects Versions: 2.2.0
Environment: RHEL 6.4
Reporter: Jinghui Wang
Fix For: 2.2.0
When running test TestMRAppComponentDependencies, surefire exits with the
following message:
Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.16:test
(default-test) on project hadoop-mapreduce-client-app: ExecutionException;
nested exception is java.util.concurrent.ExecutionException:
java.lang.RuntimeException: The forked VM terminated without saying properly
goodbye. VM crash or System.exit called ?
The following code is found in o.a.h.mapreduce.v2.app.MRAppMaster#shutDownJob,
which the test case inherits. So, before the test testComponentStopOrder
completes in TestMRAppComponentDependencies, shutDownJob finishes executing and
exits the JVM, thus causing the error. Based on the comment, the System.exit(0)
is there as a workaround for before HADOOP-7140. Since the patch for
HADOOP-7140 is committed in branch-2, are we safe to remove the System.exit
call now.
//Bring the process down by force.
//Not needed after HADOOP-7140
LOG.info("Exiting MR AppMaster..GoodBye!");
