[jira] [Commented] (SPARK-9688) Improve spark-ec2 script to handle
users that are not root
[ https://issues.apache.org/jira/browse/SPARK-9688?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14660215#comment-14660215 ]
Sean Owen commented on SPARK-9688:
----------------------------------
I think this is more of a question for user@ at this stage, since it's not clear there's a change that's needed. Also, the EC2 support is really at https://github.com/amplab/spark-ec2 now BTW.

> Hi,
> I was trying to use the spark-ec2 script from Spark to create a new Spark cluster wit an user different than root (--user=ec2-user). Unfortunately the part of the script that attempts to copy the templates into the target machines fail because it tries to rsync /etc/* and /root/*
> This is the full traceback
> rsync: recv_generator: mkdir "/root/spark-ec2" failed: Permission denied (13)
> *** Skipping any contents from this failed directory ***
> sent 95 bytes received 17 bytes 224.00 bytes/sec
> total size is 1444 speedup is 12.89
> rsync error: some files/attrs were not transferred (see previous errors) (code 2 3) at main.c(1039) [sender=3.0.6]

> Is there a workaround for this? I want to improve security of our operations by avoiding user root on the instances.
