hadoop - How can we pass List<Text> as Mapper output? -


i working on problem of map-reduce. stuck @ 1 point how can pass list<text> mapper output? possible or not? if yes, how can tell configuration mapper output class?

you may use arraywritable class value object mapper class. please refer below code snippet mapper class,

arraywritable arraywritable = new arraywritable(text.class);  text [] textvalues = new text[2]; textvalues[0] = new text("value1"); textvalues[1] = new text("value1");  arraywritable.set(textvalues ); context.write(key , arraywritable );

set value class following in driver class,

job.setmapoutputvalueclass(arraywritable.class);
