Hi, all
I'm writing my own map-reduce code using eclipse with hadoop plug-in.
I've specified input and output directories in the project property.
(two folders, namely input and output)
My problem is that each time when I do some modification and try to
run it again, i have to manually delete the previous output in HDFS,
otherwise there will be error.
Can anyone kindly suggest how to just simply overwrite the result?
Best regards,
Xin
Try HadoopUtil.delete(conf, outputPath); where outputPath is a Path(
file or directory)
