PIG-2207 caused the grouping to be changed. What's causing counter numbers to
be changed? [~cheolsoo], [~daijy] comments?

>
> This is a regression of PIG-2207.
> The Warning_4 e2e test fails because expected warning messages are not
> printed to stderr. I confirmed that the following lines are present w/o
> PIG-2207, whereas they are not w/ PIG-2207.
