Subject what is the difference between the two packages "org.apache.hadoop.mapreduce" and "org.apache.hadoop.mapred"?
Date Tue, 26 Apr 2011 12:17:15 GMT
hi
    when i read the source of mapred, i find there're a lot of classes with
the same names between "org.apache.hadoop.mapreduce" and
"org.apache.hadoop.mapred", such as "org.apache.hadoop.mapreduce.Counters"
and "org.apache.hadoop.mapred.Counters", why does this happen? why not
define only one Counters instead? what is the difference between the two
packages "org.apache.hadoop.mapreduce" and "org.apache.hadoop.mapred"?

    thx
