issue about terasort read partition file from local fs instead HDFS

[ch huang <ju...@gmail.com>]

hi,maillist:
              i try to use terasort to benchmark my cluster ,when i run it
,i found tearsort try to read partition file from local filesystem
not HDFS,i see a partition file in HDFS ,when i copy this file into local
filesystem,run terasort again ,it's work fine ,but it run on local host
instead of cluster ,why? and how can i let it run on cluster?
