---------------------------------------
Summary: Use a junit temp folder for TestingTaskManagerRuntimeInfo
tmpWorkingDirectory
Key: FLINK-26686
URL: https://issues.apache.org/jira/browse/FLINK-26686
Project: Flink
Issue Type: Improvement
Components: Runtime / Configuration
Reporter: Marios Trivyzas
Following FLINK-26418, maybe it's a good idea to not expose a constructor
without the *tmpWorkingDirectory* as this ends up in creating the ROCKSDB
folders inside */tmp* (which at least is an improvement over having them
created in the given {*}CWD{*}, ending up in the root folder of each given
module (i.e: {*}flink-table/flink-table-planner{*}).
If the *tmpWorkingDirectory* is a mandatory argument then the consumers (IT
tests) would have to provide this directory and they can use the standard junit
*TemporaryFolder.newFolder()* so that the directories are automatically deleted
after the tests are run, and devs can find those directories under the
build/test folder of each module and not in an unorganized structure in */tmp*
(or windows user's tmp folder).
