Hi, I am upgrading my code from hadoop-0.19.2 to hadoop-0.20.2, during the process I found that there was no KeyValueTextInputFormat class which exists in hadoop-0.19.2. It's so strange that this version of hadoop does not come with this commonly used InputFormat. I have taken a look at the "SecondarySort.java" example code, it uses TextInputFormat and StringTokenizer to split each line, it is ok but kinda awkward to me.
Do I have to implement a new InputFormat myself or there's a KeyValueTextInputFormat that exists somewhere I didn't notice? Thank you. Kevin Tse
