tail will work as well.. ??? but i want to extract just (say) n lines out of
this file?

hadoop fs -copyToLocal
or
hadoop fs -get
It copies the whole file and won't be able just to copy part of the file, what
is interesting is there is a "tail" command but no "head".

Ok,
A very stupid question...
I have a large file in
/user/input/foo.txt
I want to copy first 100 lines from this location to local filesystem...
And the data is very sensitive so i am bit hesistant to experiment.
What is the right way to copy sample data from hdfs to local fs.
