Re: [jira] [Commented] (MAHOUT-904) SplitInput should support randomizing the input

Thanks Lance. If I understand you correctly you're proposing the following: Map: (K1,V1) -> (K2,V2) V2 = V1 K2 = hashcode(K1) emit(K2,V2) Combine: (K2,V2) -> (K3,V3) (e.g. if we want to keep 10% of samples) if ( ! K2%10 ) { V3 = V2 K3 = K2 emit(K3, V3) } Reduce: (K3,V3) S
