Jungtaek Lim created SPARK-11765:
------------------------------------
Summary: Avoid assign UI port between browser unsafe ports (or
just 4045: lockd)
Key: SPARK-11765
URL: https://issues.apache.org/jira/browse/SPARK-11765
Project: Spark
Issue Type: Improvement
Reporter: Jungtaek Lim
Priority: Minor
Spark UI port starts on 4040, and UI port is incremented by 1 for every
confliction.
In our use case, we have some drivers running at the same time, which makes UI
port to be assigned to 4045, which is treated to unsafe port for chrome and
mozilla.

http://www-archive.mozilla.org/projects/netlib/PortBanning.html#portlist
We would like to avoid assigning UI to these ports, or just avoid assigning UI
port to 4045 which is too close to default port.
If we'd like to accept this idea, I'm happy to work on it.
