> I found TezClientUtils has method ensureStagingDirExists.It will check
> whether the path "stagingArea" exists, if it exists, check the permission, if
> not, call the function "TezCommonUtils.mkDirForAM" to create.But in method
> mkDirForAM,it use mkdir(path, permission) to create, if umask too strict such
> as 777,this directory will set with 000 permission.So we need to ensure the
> directory has right permission.
