is it suppose to be kind of hidden on how to subscribe to the mailing list?
When I go to http://apache-spark-user-list.1001560.n3.nabble.com/ (the link that comes up on a google search for the spark mailing list) I was able to register on nabble.com with no issues. Then when I tried posting it says I needed to subscribe to the mailing list and gave a link to subscribe. The subscribe seems to try to subscribe to user-al...@spark.apache.org. after hitting reply and nothing cumming back I realized something was not quite right. I decided to send an email to user-subscr...@spark.apache.org to subscribe to the list instead of what the email was saying user-allow-subscr...@spark.apache.org. After sending the email to user-subscr...@spark.apache.org I got back a proper message that allowed me to join the list. I'm sure I am not the only one that is getting confused connecting to the mailing list.
