My CSV file looks this way
ID COL1 COL2 COL3
1 a b c
2 d e f
and i want my output results as
There is one way i could do this -Use 3 maps (Map1 has ID,COL1 mapped & Map2 has ID,COL2 mapped & Map3 has ID,COL3 mapped) and combine results from three Maps and use it further.
But is there any better way to achieve this ?
