2. Select the Define a storage configuration component check box and select the tHDFSConfiguration component to be used.
3. From the Model type drop-down list, select Kmeans model.
4. Select the Model on filesystem radio button and enter the directory in which the KMeans model is stored.

   In this case, the tPredict component contains a read-only column called *label* in which the model provides the labels of the clusters.
5. Double-click tFileOutputDelimited to open its Component view.

6. Select the Define a storage configuration component check box and select the tHDFSConfiguration component to be used.
7. In the Folder field, browse to the location in HDFS in which you want to store the prediction result.
8. From the Action drop-down list, select Overwrite. But if target folder does not exist, select Create.
9. Select the Merge result to single file check box and then the Remove source dir check box.
10. In the Merge file path field, browse to the location in HDFS in which you want to store the merged prediction result.
