Hey Luca,
We discussed this in Research and it all sounds good to us with one
question below. If something else arises, we'll ping you. Thanks for the
heads up!
We assumed that instructing Spark to use a
predefined
range of random ports was not possible, but in
https://phabricator.wikimedia.org/T170826 we discovered that there is a
way
(that seems to work fine from our tests).
Will we need to change anything in our configuration or will this be
automatic?
On the stat hosts the change is already live and your new spark sessions
will pick it up automatically, on the notebooks we'll need to restart the
spark sessions before enabling the firewall. I am planning to contact all
the owners of a Spark session on notebook100[3,4], so if anybody sees an
email from me then there will be an action to do, otherwise none :)
Luca
