Chiwan Park updated FLINK-3878:
-------------------------------
Component/s: Local Runtime
Distributed Runtime
> File cache doesn't support multiple duplicate temp directories
> --------------------------------------------------------------
>
> Key: FLINK-3878
> URL: https://issues.apache.org/jira/browse/FLINK-3878
> Project: Flink
> Issue Type: Bug
> Components: Distributed Runtime, Local Runtime
> Affects Versions: 1.1.0, 1.0.2
> Reporter: Ken Krugler
> Attachments: FLINK-3878.patch
>
>
> Based on
> https://ci.apache.org/projects/flink/flink-docs-master/setup/config.html, you
> should be able to specify the same temp directory name multiple times. This
> works for some of the Flink infrastructure (e.g. the TaskManager's temp file
> directory), but not for FileCache.
> The problem is that the FileCache() constructor tries to use the same random
> directory name for each of the specified temp dir locations, so after the
> first directory is created, the second create fails.
