[jira] [Created] (FLINK-3878) File cache doesn't support multiple
duplicate temp directories
Ken Krugler created FLINK-3878:
----------------------------------
Summary: 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
Affects Versions: 1.0.2
Reporter: Ken Krugler
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.
