> Currently, we’ll generate a jaas file under tmp directory[1], files generated the jobs which run on the same machine will all run into the same directory /tmp, this may be problematic because of the reasons:
>  * Run out of inode for the disk which directory /tmp on
>  * The performance of /tmp directory will affect the read/write performance of jaas file.
>  
> So we propose to change place the jaas file under the {{CoreOptions.TMP_DIRS}} directory other than the /tmp directory.
