HI,
The following is the scenario I have: I have a java program that reads multiple files from the disk. * There are 3 files (A,B,C) that are read and populated into 3 collections (arraylist). * There are 2 files input1 and input2 that act as input to my program. * I search a keyword in file input1 and find the ID corresponding to the matching entries. * This ID is used in file input2 to fetch the entries corresponding to it. There has to be a join between input1 and input2 I want to convert it into a map reduce program, is that possible? How can we read multiple input files in the mapper, can we read files from the disk.
