Hi, Suraj. I am reading the "BSP Programming Model<https://issues.apache.org/jira/secure/attachment/12528218/ApacheHamaBSPProgrammingmodel.pdf>" pdf in Hama wiki you introduced to me. I wonder there is a type error in this pdf. See the "BSPPeer<NullWritable, NullWritable, Text, DoubleWritable,DoubleWritable> peer" in the code block in page 16. Is it should be "BSPPeer<NullWritable, NullWritable, Text, DoubleWritable> peer" ?
BTW, this pdf file is a wonderful guide for me,thanks . Walker. 2012/9/13 顾荣 <[email protected]> > Hi, Suraj. > > Thanks so much.
