Subject [jira] [Commented] (SPARK-1204) EC2 scripts upload private key
Date Sun, 11 Jan 2015 06:00:37 GMT

    [ https://issues.apache.org/jira/browse/SPARK-1204?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14272828#comment-14272828

Shivaram Venkataraman commented on SPARK-1204:
----------------------------------------------

No - This was fixed in https://github.com/apache/spark/commit/b98572c70ad3932381a55f23f82600d7e435d2eb

We generate a new ssh key on the master for each cluster launch and then copy that to all
the slave machines

> The EC2 scripts upload the private key that you supply.
> At least, this needs to be clearly documented in --help.
> Ideally, only the public key would be uploaded to all the instances. For the instances
to connect to one another, a fresh key should be generated (locally or on the master).
