can we change this to a ", e" instead of a "+ e" that way we can get the
stack trace in the logs too.
> (Security) Netty SASL Authentication
> ------------------------------------
>
> Key: STORM-348
> URL: https://issues.apache.org/jira/browse/STORM-348
> Project: Apache Storm (Incubating)
> Issue Type: Bug
> Reporter: Robert Joseph Evans
> Assignee: Raghavendra Nandagopal
> Labels: security
> Attachments: Storm-Netty Authentication.pdf
>
>
> Currently The Netty transport does no authentication at all. You can encrypt
> the tuples being sent, but that is a huge performance hit for many cases that
> do not need it. We should support simple SASL authentication when Netty
> first connects to an external process. We probably want to use something
> similar to what we do for ZK, and generate a random secret for each topology.
