Reduce number of FS permissions and redundant FS operations

    Details

    • Type: Improvement
    • Status: Closed
    • Priority: Minor
    • Resolution: Fixed

      Description

      Some examples are given below.
      1. When creating stage directory, FileUtils sets the directory permissions by running a set of chgrp and chmod commands. In systems like S3, this would not be relevant.
      2. In some cases, fs.delete() is followed by fs.exists(). In this case, it might be redundant to check for exists() (lookup ops are expensive in systems like S3).
