Nicholas Chammas commented on SPARK-3398:
-----------------------------------------
OK, so you're invoking {{spark-ec2}} from an Ubuntu server. I wonder if that
matters any, specifically when we make [this
call|https://github.com/apache/spark/blob/4b55482abf899c27da3d55401ad26b4e9247b327/ec2/spark_ec2.py#L615].
What happens if you replace the code at that line with this version?
{code}
ret = subprocess.check_call(
ssh_command(opts) + ['-t', '-t', '-o', 'ConnectTimeout=3',
'%s@%s' % (opts.user, host),
stringify_command('true')]
)
{code}
This will just print SSH's output to the screen instead of suppressing it. If
anything's going wrong, it should be more obvious that way.
> Have spark-ec2 intelligently wait for specific cluster states

> Key: SPARK-3398
> URL: https://issues.apache.org/jira/browse/SPARK-3398
> Project: Spark
> Issue Type: Improvement
> Components: EC2
> Reporter: Nicholas Chammas
> Assignee: Nicholas Chammas
> Priority: Minor
> Fix For: 1.2.0
>
>
> {{spark-ec2}} currently has retry logic for when it tries to install stuff on
> a cluster and for when it tries to destroy security groups.
> It would be better to have some logic that allows {{spark-ec2}} to explicitly
> wait for when all the nodes in a cluster it is working on have reached a
> specific state.
> Examples:
> * Wait for all nodes to be up
> * Wait for all nodes to be up and accepting SSH connections (then start
> installing stuff)
> * Wait for all nodes to be down
> * Wait for all nodes to be terminated (then delete the security groups)
> Having a function in the {{spark_ec2.py}} script that blocks until the
> desired cluster state is reached would reduce the need for various retry
> logic. It would probably also eliminate the need for the {{--wait}} parameter.
