[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=15864595#comment-15864595 ]
Julian Gamble commented on SPARK-9279:
--------------------------------------
This is a serious issue in Cloud/Docker environments when trying to look at Spark workers through a proxy (like Fabio) that defaults to 80. You need the worker to publish its port on 80 (regardless of what port the docker host opens) so that its published port is 80 for the proxy. (You can work around this with Ambassadors - but other applications don't force you to do this.)

> 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.
> Full output from a sample run below:
