Drop a tHDFSInput component, a tHDFSOutput component and a tJDBCOutput component in the workspace. The tHDFSInput component reads data from the Hadoop

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
If from scratch, you have to drop a tSortRow component and a tUniqRow component, too.
- Connect tHDFSInput to tSortRow using the Row > Main link and accept to get the schema of tSortRow.
- Connect tUniqRow to tHDFSOutput using Row > Uniques and to tJDBCOutput using Row > Duplicates.
