Description

SecureBulkLoadManager will create baseStagingDir if not exist. start method use 
fs.mkdirs(baseStagingDir, PERM_HIDDEN); to create directory with permission -rwx–x–x.BUT if umask is too strict such as 077 ,this directory will create with 0700 so it too strict for GROUP and OTHER user to own execute permission
