> When we get a batch with record count 0 and empty schema from one of the senders in the
merge receiver, 
> the following exception is thrown sometimes.
> Problem is that merge receiver is reading from the wrong sender when first batch is empty
from one of the senders.
> When first batch is empty, we are continuing without moving to the next sender.
> Error: SYSTEM ERROR: IllegalStateException: Cleanup before finished. 0 out of 1 streams
have finished
> Fragment 0:0
