If you'd like to reset storage file system to local, just edit configuration `tsfile_storage_fs` to `LOCAL`. In this situation, if you have already had some data files on HDFS, you should either download them to local and move them to your config data file folder (`../server/target/iotdb-server-0.9.0-SNAPSHOT/data/data` by default), or restart your process and import data to IoTDB.
