Running script asynchronously

Hi all

Is there a way to run script on hosts asynchronously instead of using

       client.runScriptOnNodesMatching(runningInGroup(group), script,
                  overrideCredentialsWith(creds));

I would be grateful if somebody can help me to clarify this.

The method returns a ListenableFuture you can use to add custom
callbacks. Take a look at the Guava wiki [1] explaining how it works
and to find some examples examples of how to use it.

Hi all

when we submit a job using submitScriptOnNode method how do we monitor the
state of the job and how to find the execution has finished using jclouds.
I would be grateful if somebody can clarify this.

Hi Nipun,

You can use the "submitScriptOnNode" method, which returns a Future, to do
that. It does not accept a predicate, so youl'll have to call it once for
each node in the group.

HTH!
