Rick Kellogg updated STORM-333:
-------------------------------
Component/s: storm-core
> Kryo Serializers not threadsafe
> -------------------------------
>
> Key: STORM-333
> URL: https://issues.apache.org/jira/browse/STORM-333
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-core
> Reporter: Fabian Lange
>
> I am troubleshooting a customer problem, so please forgive me if I don't know
> an important implementation detail, but from the looks of it
> backtype.storm.serialization.KryoValuesSerializer
> and relatives are not threadsafe.
> SerializableSerializer is, and can be used by many threads at the same time.
> The others are not, because they share buffers as internal state and are not
> synchronized.
> I can put together a PR on github if you could confirm that this is a bug and
> not intended.
