>                 Key: SPARK-9279
>                 URL: https://issues.apache.org/jira/browse/SPARK-9279
>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core
>    Affects Versions: 1.4.1
>         Environment: Ubuntu Trusty running in a docker container
>            Reporter: Omar Padron
>            Priority: Minor
>
> When trying to start a spark master server as root...
> {code}
> export SPARK_MASTER_PORT=7077
> export SPARK_MASTER_WEBUI_PORT=80
> spark-class org.apache.spark.deploy.master.Master \
>     --host "$( hostname )" \
>     --port "$SPARK_MASTER_PORT" \
>     --webui-port "$SPARK_MASTER_WEBUI_PORT"
> {code}
> The process terminates with IllegalArgumentException "requirement failed: startPort should
be between 1024 and 65535 (inclusive), or 0 for a random free port."
> But, when SPARK_MASTER_WEBUI_PORT=8080 (or anything >1024), the process runs fine.
> I do not understand why the usable ports have been arbitrarily restricted to the non-privileged.
 Users choosing to run spark as root should be allowed to choose their own ports.
