> Netty Initialization is sometimes very slow
> -------------------------------------------
>
> Key: FLINK-930
> URL: https://issues.apache.org/jira/browse/FLINK-930
> Project: Flink
> Issue Type: Bug
> Reporter: Stephan Ewen
> Assignee: Ufuk Celebi
> Labels: performance
>
> I often see the initialization of Netty taking 3 seconds and then failing
> with the message
> "WARN io.netty.util.internal.ThreadLocalRandom - Failed
> to generate a seed from SecureRandom within 3 seconds. Not enough entrophy?"
> This adds to every single run a 3 seconds delay, which is often more than the
> test time and causes our builds to run out of time.
