Eli Collins updated HDFS-3582:
------------------------------
Description:
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). Unfortunately Surefire doesn't
retain the log output (see SUREFIRE-871) so the test log is empty, we don't
know which part of the test triggered which exit in HDFS. To make this
debuggable, 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).
