Hello
In my use case, I need to build a single big sequence file. The key value pairs are generated by map processes and a single reducer is used to generate the sequence file. My value is a floatwritable (a list of float values). I use hadoop streaming 2.4. i have a mapper that prints key value pairs like this println "${key}@${value}" In my reducer, I need to collect them and append them into a sequence file. However, in reducer, the input is a string and I do not know how to convert 'value' into floatWritable? any clue here? thanks Rab
