multiple hosts execute different ssh command concurrently

[snecker]

Hi，I want to login in multiple hosts with different password and excute different command concurrently, so I tried the following groovy code

String vmIp = "host1 host2 host3 host4"
ParallelClient pc = new ParallelClient()
pc.prepareSsh().setConcurrency(10)
	.setSshLoginType(SshLoginType.PASSWORD)
	.setReplacementVarMapNodeSpecific([
	    "host1": new StrStrMap(["cmd": "echo 1", "userName": "user", "password": "pwd"]),
	    "host2": new StrStrMap(["cmd": "echo 2", "userName": "user", "password": "pwd"]),
	    "host3": new StrStrMap(["cmd": "echo 3", "userName": "user", "password": "pwd"]),
	    "host4": new StrStrMap(["cmd": "echo 4", "userName": "user", "password": "pwd"])])
	.setTargetHostsFromString(vmIp)
	.setSshCommandLine("\$cmd")
	.setSshUserName("\$userName")
	.setSshPassword("\$password")
	.setSshPort(22)
	.execute(new ParallecResponseHandler() {
	@Override
	public void onCompleted(ResponseOnSingleTask res, Map<String, Object> responseContext) {
		System.out.println("Responose:" + res.toString() + " host: "
				+ res.getHost() + " errmsg: "
				+ res.getErrorMessage());
	}
});
pc.prepareSsh()
pc.releaseExternalResources();

but it doesnt work,the log is
