---------------------------------------

             Summary: Duplicate TypeSerializer when writing RocksDB Snapshot
                 Key: FLINK-5154
                 URL: https://issues.apache.org/jira/browse/FLINK-5154
             Project: Flink
          Issue Type: Bug
          Components: Streaming
            Reporter: Aljoscha Krettek
            Assignee: Stefan Richter
            Priority: Blocker
             Fix For: 1.2.0, 1.1.4


Some {{TypeSerializers}} are not thread safe (for example {{KryoSerializer}}) we have to {{duplicate()}} them when using concurrently, as happens when performing a RocksDB snapshot.
