Subject [jira] [Created] (HDFS-3582) Hook System.exit in MiniDFSCluster
Date Mon, 02 Jul 2012 00:17:54 GMT
Eli Collins created HDFS-3582:

             Summary: Hook System.exit in MiniDFSCluster
                 Key: HDFS-3582
                 URL: https://issues.apache.org/jira/browse/HDFS-3582
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: test
    Affects Versions: 2.0.0-alpha
            Reporter: Eli Collins
            Assignee: Eli Collins
            Priority: Minor

Occasionally the tests fail with "java.util.concurrent.ExecutionException: org.apache.maven.surefire.booter.SurefireBooterForkException:
Error occurred in starting fork, check output in log" because the NN is exit'ing (via System.exit
or Runtime.exit). Let's hook this in MiniDFSCluster  via installing a security manager that
overrides checkExit (ala TestClusterId) or mock out System.exit in the code itself. I think
the former is preferable though we'll need to keep the door open for tests that want to set
their own security manager (should be fine to override this one some times).
