Fabian Lange updated STORM-333:
-------------------------------

    Summary: Kryo Serializers not threadsafe  (was: Kyro Serializers not threadsafe)

> Kryo Serializers not threadsafe
> -------------------------------
>
>                 Key: STORM-333
>                 URL: https://issues.apache.org/jira/browse/STORM-333
>             Project: Apache Storm (Incubating)
>          Issue Type: Bug
>            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.
