> 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 easier to debug let's hook all daemon process exits when running the tests.
