[b]Hi,,
while I am studying the part of splitting the input file into splits in hadoop code , I found that after he splits the input file he used that function :
and that function created 4 files in the harddisk : job.split , job.splitmetainfo , job.split.crc and job.splitmetainfo.crc
and when I open the class JobSplitWriter code, there is a comment : The class that is used by the Job clients to write splits (both the meta and the raw bytes parts)
I don't understand what is the use of this function ?
thanks,,[/b]
