Omar Padron commented on SPARK-9279:
------------------------------------
Forgive me for not being fully aware of the various terminology. Is the
"driver" in this case the spark master server?
> Spark Master Refuses to Bind WebUI to a Privileged Port
> -------------------------------------------------------
>
> Key: SPARK-9279
> URL: https://issues.apache.org/jira/browse/SPARK-9279
> Project: Spark
> Issue Type: Improvement
> Components: Web UI
> 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.
