Match column 8 in file 1 with column 2 in file 2 and replace..
I am looking at the NR==FNR posts and trying to use them to achieve the following but I am not getting it.
I have 2 files. I want to match column 8 in file 1 with column 2 in file 2. When they match I want to replace column 9 in file 1 with column 1 in file 2.

This is and extract from file 1

Code:
MDSA01,20:00:54:7f:ee:4a:29:80,OAKS VSAN 4,1,12,0x2a1541,4 Gbps ,10000000c964e8e4,SEIITCDB16
MDSB01,20:00:54:7f:ee:56:ab:c0,OAKS VSAN 4,1,12,0xe512c0,4 Gbps ,10000000c964ec06,SEIITCDB16
MDSA01,20:00:54:7f:ee:4a:29:80,OAKS VSAN 4,port-channel, 2,0x2a0062,N/A,20000025b550137d,HOSTNAME_INFO
MDSA01,20:00:54:7f:ee:4a:29:80,OAKS VSAN 4,port-channel, 2,0x2a0063,N/A,20000025b55011dc,HOSTNAME_INFO
MDSB01,20:00:54:7f:ee:56:ab:c0,OAKS VSAN 4,1,14,0xe51ac0,4 Gbps ,10000000c95de114,SEIMOBDB03
MDSA01,20:00:54:7f:ee:4a:29:80,OAKS VSAN 4,1,15,0x2a0d00,8 Gbps ,10000000c9ae12ec,SEIDEVDB61


This is file 2

Code:
SEIESXPD21,20000025b550101c
SEIESXPD21,20000025b550137d
SEIESXPD22,20000025b55011dc
SEIESXPD22,20000025b550135d
SEIESXPD23,20000025b55011bc
SEIESXPD23,20000025b550133d


So in this example I want to replace HOSTNAME_INFO in file 1 with SEIESXPD21 when 20000025b550137d in column 8 in file 1 matches column 2 in file 2. and the same goes for 20000025b55011dc. I want to replace HOSTNAME_INFO with SEIESXPD22 in file 1.

The output should look like this.

Code:
MDSA01,20:00:54:7f:ee:4a:29:80,OAKS VSAN 4,1,12,0x2a1541,4 Gbps ,10000000c964e8e4,SEIITCDB16
MDSB01,20:00:54:7f:ee:56:ab:c0,OAKS VSAN 4,1,12,0xe512c0,4 Gbps ,10000000c964ec06,SEIITCDB16
MDSA01,20:00:54:7f:ee:4a:29:80,OAKS VSAN 4,port-channel, 2,0x2a0062,N/A,20000025b550137d,SEIESXPD21
MDSA01,20:00:54:7f:ee:4a:29:80,OAKS VSAN 4,port-channel, 2,0x2a0063,N/A,20000025b55011dc,SEIESXPD22
MDSB01,20:00:54:7f:ee:56:ab:c0,OAKS VSAN 4,1,14,0xe51ac0,4 Gbps ,10000000c95de114,SEIMOBDB03
MDSA01,20:00:54:7f:ee:4a:29:80,OAKS VSAN 4,1,15,0x2a0d00,8 Gbps ,10000000c9ae12ec,SEIDEVDB61

I have tried the following

Code:
awk -F, 'NR==FNR{A[$2]=$2;next}$8 in A{$9=A[$2]}1' file2.out file1.out

But I am getting a blank entry for column 9 in file 1 when I do this. That is when the matching occurs. Can somebody please help me with this?

locale::codes::langvar

Locale::Codes::LangVar(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangVar(3pm)

NAME

       Locale::Codes::LangVar - standard codes for language variation identification

SYNOPSIS

	  use Locale::Codes::LangVar;

	  $lvar = code2langvar('acm');		       # $lvar gets 'Mesopotamian Arabic'
	  $code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langvar_codes();
	  @names   = all_langvar_names();

DESCRIPTION

       The "Locale::Codes::LangVar" module provides access to standard codes used for identifying language variations, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language variations. A code set may be specified using either a name, or
       a constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lvar = code2langvar('en','alpha-2');
	  $lvar = code2langvar('en',LOCALE_CODE_ALPHA_2);

       The codesets currently supported are:

       alpha
	   This is the set of alphanumeric codes from the IANA language registry, such as 'arevela' for Eastern Armenian.

	   This code set is identified with the symbol "LOCALE_LANGVAR_ALPHA".

	   This is the default code set.

ROUTINES

       code2langvar ( CODE [,CODESET] )
       langvar2code ( NAME [,CODESET] )
       langvar_code2code ( CODE ,CODESET ,CODESET2 )
       all_langvar_codes ( [CODESET] )
       all_langvar_names ( [CODESET] )
       Locale::Codes::LangVar::rename_langvar  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangVar::add_langvar  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangVar::delete_langvar  ( CODE [,CODESET] )
       Locale::Codes::LangVar::add_langvar_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangVar::delete_langvar_alias  ( NAME )
       Locale::Codes::LangVar::rename_langvar_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangVar::add_langvar_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangVar::delete_langvar_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
