Subject [GitHub] flink issue #2083: [FLINK-3713] [clients, runtime] Use user code class loade...
Date Sat, 11 Jun 2016 08:04:31 GMT
Github user uce commented on the issue:

    Full ack, but the problem is not just RocksDB, but also savepoints, which reference a
user class in the state descriptor, including FS snapshots. So if you configure a file backend
and use folding or reducing state, you run into the issue as well.
    What about the following: make it optional and fail with a proper error message in case
of a missing user code class. SubtaskState (previously StateForTask), which fails to dispose
the state snapshots currently only logs the Exception. We can change this to rethrow and then
we give a proper error message on failed savepoint disposal.

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
with INFRA.
