Setting up the Job

Before you begin

  • You have generated the suspect data pairs by using the tMatchPairing component.

  • You added a label next to the second record in each suspect pair to say whether it is a duplicate record or not or whether it is a possible duplicate as well:

    480060609;DFSS_AgencySiteLies_2012.csv;Catholic Charities of the Archdiocese of Chicago St. Joseph;4800 S. Paulina; st. joseph_1;;
480060609;purple_binder_early_childhood.csv;Catholic Charities Chicago - St. Joseph;4800 S Paulina Street; st. joseph_1;0.8058642705131237;YES
425760624;chapin_dfss_providers_2011_070212.csv;CHICAGO PUBLIC SCHOOLS GOLDBLATT, NATHAN R.;4257 W ADAMS; r._20;;
422560653;chapin_dfss_providers_2011_070212.csv;CHICAGO PUBLIC SCHOOLS ROBINSON, JACKIE R.;4225 S LAKE PARK AVE; r._20;0.8219437219200757;NO

    The labels used in this example are YES or NO, but you can use any label you like and more than two.

You can find an example of how to compute suspect pairs and suspect sample from source data on Talend Help Center (https://help.talend.com).

Procedure

  1. Drop the following components from the Palette onto the design workspace: tFileInputDelimited and tMatchModel.
  2. Connect the components together using the Row > Main link.
  3. Check that you have defined the connection to the Spark cluster in the Run > Spark Configuration view as described in Computing suspect pairs and suspect sample from source data.
  4. Check that you have defined the connection to the Spark cluster in the Run > Spark Configuration view. For more information about selecting the Spark mode, see the documentation on Talend Help Center (https://help.talend.com).
