Hello, Can a map task work on more than one input split? I am using hadoop-0.20.1 and in my map method I need to know the name of the file I am getting input from. I use the following code to get that:
String inputFile = ((FileSplit) context.getInputSplit()).getPath().getName(); If a map works on only one input split then I can have that code in the setup() method which would be more efficient if I am handling large amount of data. Otherwise, I have to put the code in the map() method. But this would slow me down as I have to do it for every input key value pair. I have gone through the following two pages but did not get a clear picture: http://wiki.apache.org/hadoop/HadoopMapReduce http://wiki.apache.org/hadoop/HowManyMapsAndReduces Thanks, Farhan
