Piotr Nowojski commented on FLINK-16227:
----------------------------------------
The original issue "NoClassDefFoundError" and the later reported mismatched
output seems like could be two independent errors and IMO those should be two
different tickets. Also it confused me that you are linking two different
errors, but in the description there is only one (initially I've thought that
input mismatched is something new that I've just found)
