> Execution plugin operations default mappings
> --------------------------------------------
>
> Key: ARIA-92
> URL: https://issues.apache.org/jira/browse/ARIA-92
> Project: AriaTosca
> Issue Type: Story
> Reporter: Ran Ziv
> Assignee: Tal Liron
>
> The execution plugin serves as the default plugin, i.e. if no other plugin
> was specified, it'll be used to execute scripts in operations.
> These scripts will currently only execute locally. The execution plugin also
> supports running scripts on remote machines (via SSH).
> One option is to have the parser recognize whether the node in question is
> contained inside a host node, in which case the script should be executed
> remotely (by default, yet overridable by specifying the full plugin operation
> mapping), and if not then it should be executed locally.
> Another option is to have the user specify it using special syntax, e.g.:
> "local > script.sh" and "remote > script.sh"
