string separation

You can use 2 seperate UDF to extract the 2 fields. for the leading ##, you use substring and ignore the first two values(##) and then split by #.

please use the UDF mentioned below.

use this UDF

for first name

public String StringSplit(String var1, Container container) throws StreamTransformationException{
int len = var1.length();
var1= var1.substring(2,len);
String arr[] = var1.split("#");
return arr[0];

for last name

public String StringSplit(String var1, Container container) throws StreamTransformationException{
int len = var1.length();
var1= var1.substring(2,len);
String arr[] = var1.split("#");
return arr[1];

Hi

You can use REGEX in the UDF to achieve this

Include 2 parameters in the UDF Say

a - [input (##Ram#Kumar##) ]

b - [Index values for first name (2) and last name (4)]

Imports: java.util.regex.*;

Parameters:

a, b

  int indexVal = Integer.parseInt(b); 
 String pattern = "(##)(.*)(#)(.*)(##)";   // first (.*) is first name - index val is 2   and last name index value is 4
 Pattern d = Pattern.compile(pattern);
 Matcher m = d.matcher(a);
            if(m.find())
            {
                a = m.group(indexVal);
              
            }

return a;

Use the same code for different fields by changing the constant(index values) in the mapping.

you can refer the below forum discussion further as srini suggest...

Separator UDF

Hi Pushpa.

Use one UDF and two parameters one for string and the other the position,

value : String (e.g ##FName#LName)

pos : Position that you want.

String result = "";
String array01[] = value.split("##");
String array02[] = array01[1].split("#");
result = array02[pos];
return result;
