-------------------------------------
Summary: Introduce safety net for closing file system streams
Key: FLINK-4910
URL: https://issues.apache.org/jira/browse/FLINK-4910
Project: Flink
Issue Type: Improvement
Reporter: Stefan Richter
Streams that are opened through {{FileSystem}} must be closed at the end of
their life cycle. However, we found hints that some code forgets to close such
streams.
We should introduce i) a mechanism that closes leaking unclosed streams after
usage and ii) provides logging that helps us to track down and fi the sources
of such leaks.
