-----------------------------------
Summary: LibraryCacheManager should track execution IDs of library
registrations
Key: FLINK-1205
URL: https://issues.apache.org/jira/browse/FLINK-1205
Project: Flink
Issue Type: Bug
Components: Distributed Runtime
Affects Versions: 0.8-incubating
Reporter: Stephan Ewen
Fix For: 0.8-incubating
Currently, it is hard to guarantee that on a failed execution attempt, the
libraries are de-registered exactly once. Only references per JobId are
tracked. If we track the registered ExecutionAttempts, we can make sure we
de-register only if we have not yet de-registered that execution attempt.
