Subject [jira] [Created] (FLINK-9762) CoreOptions.TMP_DIRS wrongly managed on Yarn
Date Thu, 05 Jul 2018 10:52:00 GMT
Oleksandr Nitavskyi created FLINK-9762:

             Summary: CoreOptions.TMP_DIRS wrongly managed on Yarn
                 Key: FLINK-9762
                 URL: https://issues.apache.org/jira/browse/FLINK-9762
             Project: Flink
          Issue Type: Bug
          Components: YARN
    Affects Versions: 1.5.0
            Reporter: Oleksandr Nitavskyi

The issue on Yarn is that it is impossible to have different LOCAL_DIRS on JobManager and
TaskManager, despite LOCAL_DIRS value depends on the container.

The issue is that CoreOptions.TMP_DIRS is configured to the default value during JobManager
initialization and added to the configuration object. When TaskManager is launched the appropriate
configuration object is cloned with LOCAL_DIRS which makes sense only for Job Manager container.
When YARN container with TaskManager from his point of view CoreOptions.TMP_DIRS is always
equal either to path in flink.yml or to the or to the LOCAL_DIRS of Job Manager (default behaviour).
Is TaskManager’s container do not have an access to another folders, that folders allocated
by YARN TaskManager cannot be started.
