A small correction to RavinderSingh13's yields
Code:
awk '
FNR==NR         {q    = $1
                 $1   = $2 = ""
                 A[q] = $0
                 next
                }
                {print $0, A[$2]
                }
'  file1 file2
  1  2 >CR=                 2 VWB   0 -1 -1 -1 -1 -1 -1 -1 -1 -1
  2  2 >JC                  2 GBR   0 -1 -1 -1 -1 -1 -1 -1 -1 -1
  3                            
  4  6 >CR                  6 D

which is as close to the requested output as you can get. Please note that the desired output given in post#1 does NOT satisfy the specification as there's NO match of file2's line 4's 6 in file1!

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME
xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files SYNOPSIS
xzcmp [cmp_options] file1 [file2] xzdiff [diff_options] file1 [file2] lzcmp [cmp_options] file1 [file2] lzdiff [diff_options] file1 [file2] DESCRIPTION
xzcmp and xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1). All options specified are passed directly to cmp or diff. If only one file is specified, then the files compared are file1 (which must have a suffix of a supported com- pression format) and file1 from which the compression format suffix has been stripped. If two files are specified, then they are uncom- pressed if necessary and fed to cmp(1) or diff(1). The exit status from cmp or diff is preserved. The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils. SEE ALSO
cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1) BUGS
Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified. Tukaani 2009-07-05 XZDIFF(1)
