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
