@CarloM,

I tried with the code:
Code:
awk '{ 
stuff
}' file1.txt $(hadoop fs -ls /user/user/data/file2.txt)

where file1 -> reading from the local
fiel2 -> reading the file from HDFS(hadoop)

But it's saying:
Quote:
awk: cmd. line:12: (FILENAME=file1.txt FNR=5) fatal: cannot open file `Found' for reading (No such file or directory)
Not getting why it is giving error for file1 although file1.txt is exists in the local directory.When i tried removing the part $(hadoop fs -ls /user/user/data/file2.txt) and copy the file2.txt to local and give the local path like }' file1.txt file2.txt its working fine.

So it's not allowing to take the file directly from hdfs to process using awk command . How how can i do it? is there any alternative for this?
NOTE: i don't want to copy the hadoop files to local directory to acheive this

Thanks

mv

MV(1)							      General Commands Manual							     MV(1)

NAME

       mv - move or rename files

SYNOPSIS

       mv [ -i ] [ -f ] [ - ] file1 file2

       mv [ -i ] [ -f ] [ - ] file ... directory

DESCRIPTION

       Mv moves (changes the name of) file1 to file2.

       If file2 already exists, it is removed before file1 is moved.  If file2 has a mode which forbids writing, mv prints the mode (see chmod(2))
       and reads the standard input to obtain a line; if the line begins with y, the move takes place; if not, mv exits.

       In the second form, one or more files (plain files or directories) are moved to the directory with their original file-names.

       Mv refuses to move a file onto itself.

       Options:

       -i     stands for interactive mode. Whenever a move is to supercede an existing file, the user is prompted by the name of the file followed
	      by  a  question mark. If he answers with a line starting with 'y', the move continues. Any other reply prevents the move from occur-
	      ring.

       -f     stands for force. This option overrides any mode restrictions or the -i switch.

       -      means interpret all the following arguments to mv as file names.	This allows file names starting with minus.

SEE ALSO

       cp(1), ln(1)

BUGS

       If file1 and file2 lie on different file systems, mv must copy the file and delete the original.  In this case the owner name becomes  that
       of the copying process and any linking relationship with other files is lost.
