Marco Gaido 3c96937c7b [SPARK-24948][SHS] Delegate check access permissions to the file system ... ## What changes were proposed in this pull request? In `SparkHadoopUtil. checkAccessPermission`, we consider only basic permissions in order to check wether a user can access a file or not. This is not a complete check, as it ignores ACLs and other policies a file system may apply in its internal. So this can result in returning wrongly that a user cannot access a file (despite he actually can). The PR proposes to delegate to the filesystem the check whether a file is accessible or not, in order to return the right result. A caching layer is added for performance reasons. ## How was this patch tested? modified UTs Author: Marco Gaido <marcogaido91@gmail.com> Closes #21895 from mgaido91/SPARK-24948.		2018-08-06 14:29:05 -07:00
