    Hi, I manage to solve this issue. now i am able to recover all the data but 
as discussed in this thread [Data Duplicate issue] 
    how do i avoid duplicate Messages With Spark Streaming Using Checkpoint 
After Restart In Case Of Failure
    Ex. if i have published 500 records and spark processed 300 and after that 
i killed the driver and restart then  in the output directory i see the count 
of 800 messages being processed. this means spark is processing same (300) 
records again.
