Rong Rong commented on FLINK-15447:
-----------------------------------
as far as I can tell, {{java.io.tmpdir}} is controlled by SystemEnv and should
be set as a JVM launch param similar to how [~xymaqingxiang] mentioned.
Could you elaborate what does it mean by Flink-YARN default the value to
{{/tmp}}? I am guessing you mean JVM default the value to {{/tmp}} ?
* So far the only place I can see in flink yarn code utilizing this key is:
https://github.com/apache/flink/blob/release-1.10/flink-yarn/src/main/java/org/apache/flink/yarn/cli/FlinkYarnSessionCli.java#L899
Is your intention to have Flink override the JVM configuration internally and
ignore the system environment config?

> Key: FLINK-15447
> URL: https://issues.apache.org/jira/browse/FLINK-15447
> Project: Flink
> Issue Type: Improvement
> Components: Deployment / YARN
> Affects Versions: 1.9.1
> Reporter: Victor Wong
> Priority: Major
>
> Currently, when running Flink on Yarn, the "java.io.tmpdir" property is set
> to the default value, which is "/tmp".
>
> Sometimes we ran into exceptions caused by a full "/tmp" directory, which
> would not be cleaned automatically after applications finished.
> I think we can set "java.io.tmpdir" to "{{{{PWD}}}}/tmp" directory, or
> something similar. "{{{{PWD}}}}" will be replaced with the true working
> directory of JM/TM by Yarn, which will be cleaned automatically.
