[jira] [Commented] (SPARK-9279) Spark Master Refuses to Bind WebUI
to a Privileged Port
[ https://issues.apache.org/jira/browse/SPARK-9279?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14639150#comment-14639150 ]
Omar Padron commented on SPARK-9279:
------------------------------------
bq. This has nothing to do with Spark. Any Linux-like OS X requires root privileges for any process to bind to a port under 1024.
Am I missing something?
bq. When trying to start a spark master server as root...
bq. ... Users choosing to run spark as root should be allowed to choose their own ports.
I've mentioned twice that I am running spark as root, including on the very first sentence of the bug description.
In case I was not clear: I am reporting on an issue with the port selection logic that is *explicitly coded* into spark. This is not a matter of not having access to the privileged ports, but of spark explicitly refusing to bind to them. This has everything to do with spark.

>
> 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.
