service = new ServiceFactory().create(“hadoop”);
spec = new ClusterSpec();
spec.setClusterName(“myhadoopcluster”);
spec.setInstanceTemplates(ImmutableList.of(
new InstanceTemplate(1,”nn”,”jt”),
new InstanceTemplate(4,”dn”,”tt”)));
cluster = service.launchCluster(spec);
proxy = new HadoopProxy(spec, cluster);
proxy.start();
or if you like bash
$ whirr launch-cluster service-name=hadoop \
cluster-name=myhadoopcluster \
instance-templates='1 nn+jt 4 dn+tt'

Location API: Objectives

compatible metadata for service providers
jurisdiction and coordinates
collocation/billing relationships
latency and network topology
Monday, November 29, 2010
Location API: Data Draft
"amazon.us.east" {
name "Amazon US-EAST"
jurisdiction "us.va"
coordinates {
latitude 30.45
longitude 55.2
}
custom("qos") {
"datacenter.tier" 3
}
group("billing") {
peer "amazon.us.s3"
}
// provisioner-specific info (jclouds compute amazon)
}
"amazon.us.s3" {
// provisioner-specific info (jclouds blobstore)
}

Location API: Query Draft
locations = ResourceLocations.parse("/path/to/SampleLocations.conf");
matches = LocationUtils.filter(locations,
LocationFilter.Builder.newInstance()
.inJurisdiction("us")

.withCustomProperty("qos.datacenter.tier", 3)
.toFilter());
assertEquals(["amazon.us.east"], matches.values().each{it.id})
