Vincent Warmerdam commented on SPARK-8596:
------------------------------------------

done and done. 

this task feels like it is getting ready for merge. i am only wondering about 
these few lines of code in the `init.sh` script here: 
https://github.com/koaning/spark-ec2/blob/rstudio-install/rstudio/init.sh#L36-38

```
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
```

the ulimit can only be set by the root user. but it doesn't feel right to 
remove that line from the `init.sh` script in the rstudio folder. [~shivaram], 
thoughts?
