------------------------------------------
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.
