Description

Currently the logic of Initialization of TmpFileMgr is a bit tedious, we can have the TmpDir to parse and validate, and also be inherited by TmpDirHdfs and TmpDirS3 to have their own logic to parse and validate, in this way, the code could have a better structure and be easier to add more custom logic for other filesystems in future.
