Subject Iinput path pointing on an hbase table and not a text file?
Date Fri, 07 Aug 2009 14:41:44 GMT
I am using hadoop 0.19.1 and I was previously writing my application setting
a text file as an input path for the job.
Therefore the main four involved parameters were the following:*

public static class Map extends MapReduceBase implements
Mapper<LongWritable, *Text*, Text, Text> {
  public void map(LongWritable key,*Text value*, OutputCollector<Text, Text>
output, Reporter reporter) throws IOException {

public static void main(String[] args) throws Exception {
    FileInputFormat.setInputPaths(conf, *new Path(args[0]*));


*I would like to write a mapreduce application that reads from an hbase
table, summing some values etc,...and writing the output result in a
textfile. I have already created this hbase table (using version 0.19.3) I
need now to pass it's name as an input path to the job how can I do it?

I have red here and there and found out that the InputFormat shall be set to
"*TableInputFormat.class*" but what about the setInputPaths ?and the Value
class in the mapper?

Thank you,
