--------------------------------------------------------------
[~rongr] for me #2 is most close to the main concern, but we do not want to
share with others for fine-grain control on disk resource, but for a shared
location is very prone to be disk full.
There are some good points in HADOOP-2735:
_Can we add -Djava.io.tmpdir="./tmp" somewhere ?_
_so that,_
_1) Tasks can utilize all disks when using tmp_
_2) Any undeleted tmp files will be deleted by the tasktracker when task(job?)
is done._

> 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.
