>                 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.
