Hi Daniel, I see from your other thread that your HADOOP script has a line like:
#!/bin/shrm -f temp.txt I'm not sure what that is, exactly. I suspect the -f is reading from some file and the while loop you had listed read from stdin it seems. What does your input look like? I think what's happening is that you might be expecting lines of input and you're getting splits. What does your input look like? You might want to try this: -inputformat org.apache.hadoop.mapred.lib.NLineInputFormat Thanks, Tom On Sat, Dec 3, 2011 at 7:22 PM, Daniel Yehdego <dtyehd...@miners.utep.edu> wrote: > > Thanks Tom for your reply, > I think my code is reading from stdin.
