-Run the following Python code products model in `product_path` folder. Every 60 seconds, the package file of Boston house price prediction model `uci_housing.tar.gz` will be generated and uploaded to the path of HDFS `/`. After uploading, the timestamp file `donefile` will be updated and uploaded to the path of HDFS `/`.
+Run the following Python code products model in `product_path` folder(You need to modify Hadoop related parameters before running).

After uploading, the timestamp file `donefile` will be updated and uploaded to the path of HDFS `/`.
