Description

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.
