Aljoscha Krettek commented on FLINK-4603: ----------------------------------------- Yep, the user code {{ClassLoder}} can be retrieved from the {{Environment}} passed to {{AbstractStateBackend.restoreKeyedStateBackend()}}. A nicer solution would be to completely get rid of Java Serialization in the state serialization. > KeyedStateBackend cannot restore user code classes > -------------------------------------------------- > > Key: FLINK-4603 > URL: https://issues.apache.org/jira/browse/FLINK-4603 > Project: Flink > Issue Type: Bug > Components: State Backends, Checkpointing > Affects Versions: 1.2.0 > Reporter: Till Rohrmann > Priority: Blocker > Fix For: 1.2.0 > > > A user reported that he cannot restore keyed state which contains user code > classes. I suspect that we don't use the user code class loader to > deserialize the state. > The solution seems to be to forward the user code class loader to the > {{KeyedStateBackends}} when restoring state. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
