---------------------------------------

We also set "java.io.tmpdir" to "{{{{PWD}}}}/tmp" directory internally.
{code:java}
// when encapsulating the StartCommandValues for JM/TM
Path tmpDir = new Path(ApplicationConstants.Environment.PWD.$$(),
YarnConfiguration.DEFAULT_CONTAINER_TEMP_DIR);
javaOpts = "-Djava.io.tmpdir=" + tmpDir.getPath();
startCommandValues.put("jvmopts", javaOpts);
{code}
> Change "java.io.tmpdir" of JM/TM on Yarn to "{{PWD}}/tmp"

> 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.
