Why does the position of C2R affect partition numbers? C2R should not modify partition specs. The has algorithms are different between native and vanilla. The left side uses the native hash algorithm to distribute data, but the right side uses the vanilla hash algorithm. We cannot guaranttee both hash algorithms have the same result. -- This is an automated message from the Apache Git Service.
