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


Shivaram Venkataraman commented on SPARK-1204:

No - This was fixed in

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

>            Priority: Minor
> 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).
