    Should we maybe call it `updateTmpDirectoriesInConfiguration`?

>             Project: Flink
>          Issue Type: Bug
>          Components: YARN
>    Affects Versions: 1.5.0
>            Reporter: Oleksandr Nitavskyi
>            Assignee: vinoyang
>            Priority: Major
>              Labels: pull-request-available
>             Fix For: 1.5.2, 1.6.0
> 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.
