yes , but how can i get the commaSeperatedPaths? As i can't specify it handy.
it's not practicable to do that: commaSeperatedPaths_1 = "MAPPINGOUTPUT-r-00001"; commaSeperatedPaths_2 = "MAPPINGOUTPUT-r-00002"; FileInputFormat.setInputPaths(job, commaSeperatedPaths_1); FileInputFormat.setInputPaths(job, commaSeperatedPaths_2); 2009/4/7 Brian MacKay <brian.mac...@medecision.com> > > Not sure about your question: seems like you'd like to do this...? > > After you run job, your output may be like MAPPINGOUTPUT-r-00001, > MAPPINGOUTPUT-r-00002, etc. > > You'd need to set them as multiple inputs. > > FileInputFormat.setInputPaths(job, commaSeperatedPaths); > > > Brian > > -----Original Message----- > From: 皮皮 [mailto:pi.bingf...@gmail.com] > Sent: Tuesday, April 07, 2009 3:30 AM > To: core-user@hadoop.apache.org > Subject: Re: Multiple k,v pairs from a single map - possible? > > could any body tell me how to get one of the multipleoutput file in another > jobconfig? > > 2009/4/3 皮皮 <pi.bingf...@gmail.com> > > > thank you very much . this is what i am looking for. > > > > 2009/3/27 Brian MacKay <brian.mac...@medecision.com> > > > > > >> Amandeep, > >> > >> Add this to your driver..... > >> > >> MultipleOutputs.addNamedOutput(conf, "PHONE",TextOutputFormat.class, > >> Text.class, Text.class); > >> > >> MultipleOutputs.addNamedOutput(conf, "NAME, > >> TextOutputFormat.class, Text.class, Text.class); > >> > >> > >> > >> And in your reducer.... > >> > >> private MultipleOutputs mos; > >> > >> public void reduce(Text key, Iterator<Text> values, > >> OutputCollector<Text, Text> output, Reporter reporter) { > >> > >> > >> // namedOutPut = either PHONE or NAME > >> > >> while (values.hasNext()) { > >> String value = values.next().toString(); > >> mos.getCollector(namedOutPut, reporter).collect( > >> new Text(value), new Text(othervals)); > >> } > >> } > >> > >> @Override > >> public void configure(JobConf conf) { > >> super.configure(conf); > >> mos = new MultipleOutputs(conf); > >> } > >> > >> public void close() throws IOException { > >> mos.close(); > >> } > >> > >> > >> > >> By the way, have you had a change to post your Oracle fix to > >> DBInputFormat ? > >> If so, what is the Jira tag #? > >> > >> Brian > >> > >> -----Original Message----- > >> From: Amandeep Khurana [mailto:ama...@gmail.com] > >> Sent: Friday, March 27, 2009 5:46 AM > >> To: core-user@hadoop.apache.org > >> Subject: Multiple k,v pairs from a single map - possible? > >> > >> Is it possible to output multiple key value pairs from a single map > >> function > >> run? > >> > >> For example, the mapper outputing <name,phone> and <name, address> > >> simultaneously... > >> > >> Can I write multiple output.collect(...) commands? > >> > >> Amandeep > >> > >> Amandeep Khurana > >> Computer Science Graduate Student > >> University of California, Santa Cruz > >> > >> > >> > >> > >> > >> _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ > _ > >> _ > >> > >> The information transmitted is intended only for the person or entity to > >> which it is addressed and may contain confidential and/or privileged > >> material.
