You are looking for the join command. It's pesky in that it requires sorted input, so these forums are shock full of examples of doing it without sorting the input for a particular file format. Scaling up, if you have a lot of these, you might want to import them into a proper database.
awk 'NR==FNR { m[$1] = $2; next }
{ $1 = m[$1]; print }' file2 file1
Searching for NR==FNR should get you a few handfuls of examples, as well as the typical follow-up questions and problems.

Worked for me here, did you copy+paste correctly? Does Ygor's code work better for you?
This code is showing errors
awk: syntax error near line 1
Still i am getting same problem. The columns are not coming in same line. Columns are coming one below another. Please help??

The awk syntax error is often a sign that you are using "old awk". If you are on HP-UX or Sun, look around for an XPG4 version, or see if you have nawk, or mawk, or gawk.
