Hi,
I had intended to implement this requirement in the first way, but now I think the second and third are better for much less modification of current codes... Though the first way may support more than HDFS storage, it may still take a lot more time to modify codes in TsFile module based on current work.

This function can be done in many ways in IoTDB: (1) Storing all TsFiles (data files) and other files (system files, WALs) on HDFS, then use spark-tsfile to read TsFiles on HDFS. (2) Storing only TsFiles on HDFS, and other files on local file system, then use spark-tsfile to read TsFiles on HDFS. (3) Storing all files on local file system and let user use spark-iotdb-connector to read data from IoTDB, regardless where TsFiles store. Personally, I prefer the second and the third. If we use the second way, do we need the FileFactory for all Files?
