Vincent Warmerdam commented on SPARK-8596:
------------------------------------------
Rstudio doesn't want to be run as a root user in general. Rstudio doesn't have
https out of the box, so any port sniffing suddenly becomes a security risk if
somebody can use the webui to gain root access.
Instead, you can just go and add a new user
$ useradd analyst
$ passwd analyst
This user will then be able to log in. Note that in order to see rstudio, you
will need to also edit the security group for the master node to allow TCP to
connect to this port.
I'd love to help out and spend some time on these issues by the way. I've got a
small tutorial .md file ready, can I share that via Jira? Would like to double
check it with you guys because I may be doing a dirty trick. For Rstudio not to
give errors, I remove a line of code in a shell script (because this new user
is not root it cannot run `ulimit` commands).
Dirty trick (run as root):
sed -e 's/^ulimit/#ulimit/g' /root/spark/conf/spark-env.sh >
/root/spark/conf/spark-env2.sh
mv /root/spark/conf/spark-env2.sh /root/spark/conf/spark-env.sh
ulimit -n 1000000
Installing the right R version always was a bit tricky. Will follow other Jira
ticket as well.
