Here is the code and jstack trace to reproduce it:
{code}
public static void main(String[] args) throws Exception {
TezClient client = TezClient.create("foo", new TezConfiguration());
client.start();
client.stop();
System.out.println("Done");
}
{code}

Make sure you run it as Java application (main) and not JUnit since it will
essentially do System.exit.
