---------------------------------------------

             Summary: Move generated Jaas conf file from /tmp directory to Job specific directory
                 Key: FLINK-14433
                 URL: https://issues.apache.org/jira/browse/FLINK-14433
             Project: Flink
          Issue Type: Improvement
          Components: API / DataStream
            Reporter: Congxian Qiu(klion26)
             Fix For: 1.10.0


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.
