Run an asadmin command on a Node. The node may be local or remote. If it is remote then SSH is used to execute the command on the node. The args list is all parameters passed to "asadmin", but not "asadmin" itself. So an example args is: "--host", "mydashost.com", "start-local-instance", "--node", "n1", "i1"

Parameters:

node - The node to run the asadmin command on

output - A StringBuilder to hold the command's output in. Both stdout and stderr are placed in output. null if you don't want the output.

args - The arguments to the asadmin command. This includes parameters for asadmin (like --host) as well as the command (like start-local-instance) as well as an parameters for the command. It does not include the string "asadmin" itself.

Returns:

The status of the asadmin command. Typically 0 if the command was successful else 1.

Throws:

SSHCommandExecutionException - There was an error executing the command via SSH.

ProcessManagerException - There was an error executing the command locally.

UnsupportedOperationException - The command needs to be run on a remote node, but the node is not of type SSH.

IllegalArgumentException - The passed node is malformed.
