> Project: Apache Twill
> Issue Type: Bug
> Components: core, yarn
> Affects Versions: 0.6.0-incubating, 0.7.0-incubating
> Reporter: Terence Yim
> Fix For: 0.8.0
>
>
> When the AM starts the embedded Kafka, it first generates a random port (by
> creating a server socket), followed by provided that port for the Kafka
> server to bind to. It is possible that after the random port was acquired and
> before Kafka server bind to it, there is another process on the same box that
> took that port.
