Subject Question regarding network data transfer
Date Sat, 28 May 2011 23:11:13 GMT

Where exactly(Java class) does the network data transfer happen from a
mapper to a reducer ? Mapper seems to be writing data to the HDFS. Does
reducer read data from the mapper's HDFS over the network ? This is evading
me. Thanks in advance for the help.
