Description

ShuffleHandler logs SpillFile not found when there is a permission denied issue which is misleading.

 try {
        spill = SecureIOUtils.openForRandomRead(spillfile, "r", user, null);
      } catch (FileNotFoundException e) {
        LOG.info(spillfile + " not found");
        return null;
}

SecureIOUtils.openForRandomRead should log "Permission denied" or "No such file or directory" instead of generic "file not found"
