how to find data nodes on which a file is distributed to?

[CB]

Hi,

I am new to HDFS.  I read HDFS documents on the internet but I couldn't
figure out the following.
Is there a way to find a list of data nodes where a file is distributed to
 when I executed a command such as

hadoop dfs –copyFromLocal /tmp/testdata /user/chansup/test



Thanks,
