Tables and importing

[Mark]

Can someone explain what actually happens when you create a table and 
import data into using "LOAD DATA INPATH..."

I noticed that when I load the data from files already existing in HDFS 
that it actually removes the original file from its location and moves 
it under the /user/hive directory. Is there anyway I can prevent this 
from happening or is this just the way things work? At this point is the 
file modified in anyway? I have some other Hadoop jobs that rely on this 
data. Should I just update those jobs to operate on the data within 
these directories? Thanks
