Hi all, here is a wired observation. The keys in the result of *ONE* reducer are ordered like this: 18166 18169 1817 18171 18172
why is key "1817" comes after "18169"? It makes sense if that key is "18170" but it isn't! Why does it happen and basically, how does hadoop tell key1 is larger than key2? Compare their hash codes? Thanks. -Gang
