There may be a typo in the java file
Per my understanding, there would be 3 cases:
1) Run the job in a NEW Child process(maybe pseudo hadoop mode) in the same node
2) Run the job in the same process in the same node (very helpful in debugging)
3) Run the job in a real Hadoop Cluster specified
The typo may cause the second case NEVER happens, which we need in developing (debugging);
Sorry, not sure if I understand that correctly.
