Procedure

  1. Double-click this new Map/Reduce Job to open it in the workspace. The Map/Reduce components' Palette is opened accordingly and in the workspace, the crossed-out components, if any, indicate that those components do not have the Map/Reduce version.
  2. Right-click each of those components in question and select Delete to remove them from the workspace.
  3. Drop a tHDFSInput component, a tHDFSOutput component and a tJDBCOutput component in the workspace. The tHDFSInput component reads data from the Hadoop distribution to be used, the tHDFSOutput component writes data in that distribution and the tJDBCOutput component writes data in a given database, for example, a MySQL database in this scenario. The two output components replace the two tLogRow components to output data.
    If from scratch, you have to drop a tSortRow component and a tUniqRow component, too.
  4. Connect tHDFSInput to tSortRow using the Row > Main link and accept to get the schema of tSortRow.
  5. Connect tUniqRow to tHDFSOutput using Row > Uniques and to tJDBCOutput using Row > Duplicates.
