I tried on MapReduceTask_1 Partition the given data based on Country and Status

I was able to split the lines by using "\|" (pipeline) String[] words = line.split("\|"); when I tried to write data to context; I faced ArrayIndexOutofBoundsException String country = words[2]; String status = words[3]; context.write(new Text(country), new Text(status));
