klion26 opened a new pull request #10178: [FLINK-14433][DataStream] Move generated Jaas conf file from /tmp directory to Job specific directory URL: https://github.com/apache/flink/pull/10178 ## What is the purpose of the change 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. ## Verifying this change This change added tests and can be verified as follows: - *JaasModuleTest.java* ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (no) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no) - The serializers: (no) - The runtime per-record code paths (performance sensitive): (no) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (no) - The S3 file system connector: (no) ## Documentation - Does this pull request introduce a new feature? (no) - If yes, how is the feature documented? (not applicable)
