Chesnay Schepler commented on FLINK-2173:
-----------------------------------------
also, in case anyone is interested in tackling this issue: it should only be
relevant during plan construction; at runtime all paths are supplied by the
java side in a safe manner.
one potential way to fix this earlier: instead of using tempfile.gettempdir(),
infer the proper tmp directory by checking the location of the plan file, since
it should reside in the java tmp folder.
> Python uses different tmp file than Flink

> Key: FLINK-2173
> URL: https://issues.apache.org/jira/browse/FLINK-2173
> Project: Flink
> Issue Type: Bug
> Components: Python API
> Environment: Debian Linux
> Reporter: Matthias J. Sax
> Priority: Critical
>
> Flink gets the temp file path using System.getProperty("java.io.tmpdir")
> while Python uses the "tempfile.gettempdir()" method. However, both can be
> semantically different.
> On my system Flink uses "/tmp" while Pyhton used "/tmp/users/1000" ("1000" is
> my Linux user-id)
> This issues leads (at least) to failing tests.
