Hi, all I was wondering how to write all the input with the same key to a single file in the reducer ?
say, I got some intermediate outputs from mappers like that: key value -------------------- 1 annie 2 Jason 1 andy 2 Joey 1 andrew ... and I would like write all the intermediate outputs with key 1 to file "ID_1.dat", and all the intermediate outputs with key 2 to file "ID_2.data". how could I achieve that? -- YANG, Lin
