-------------------------------------

Given its a feature we recommend to users, I would suggest not to disable this 
right away. 

@uditme This is where we are now. 

Next steps could be : 
 * Dump out the logs (currently logs are printed after command succeeds) as the 
command makes progress and see where the hang is at
 * Try force killing the jvm after that point and see if it exits atleast. (I 
tried added System.exit(0) to last line of DeltaStreamer::main and it did not 
do the trick.
