-------------------------------
Assignee: vinoyang
> MiniClusterResource should set CoreOptions.TMP_DIRS
> ---------------------------------------------------
>
> Key: FLINK-9125
> URL: https://issues.apache.org/jira/browse/FLINK-9125
> Project: Flink
> Issue Type: Improvement
> Components: Tests
> Affects Versions: 1.5.0
> Reporter: Chesnay Schepler
> Assignee: vinoyang
> Priority: Major
>
> We've frequently seen test stability issues when creating temporary file that
> use hard-coded paths, like {{/tmp}}, and generally tried to instead use
> {{TemporaryFolders}} instead.
> The {{CoreOptions.TMP_DIRS}} option is used by some components to determine
> where temporary files should be placed. By default this points to
> {{System.getProperty("java.io.tmpdir")}}, which usually points to {{/tmp}}.
> This property is rarely set explicitly by tests, which leads to failures such
> as this: https://travis-ci.org/apache/flink/jobs/361515791
> {code}

> It would be nice if the MiniClusterResource inherently contains a
> {{TemporaryFolder}} which is used to configure {{CoreOptions.TMP_DIRS}} as
> well as other tmp dir options.
