我想在亚马逊实例上使用whirr启动一个实例。但是当我尝试使用标准化的whirr命令启动一个集群时，它在我的hadoop集群名称之后搜索某个目录名称为“myclutster”，它不存在。有人可以帮忙吗？

Usage: whirr launch-cluster [OPTIONS]
Option Description
------ -----------
--aws-ec2-spot-price Spot instance price (aws-ec2 specific
option)
--blobstore-cache-container The name of the container to be used
for caching local files. If not
specified Whirr will create a random
one and remove it at the end of the
session.
--blobstore-credential The blob store credential
--blobstore-identity The blob store identity
--blobstore-location-id The blob store location ID
--blobstore-provider The blob store provider. E.g. aws-s3,
cloudfiles-us, cloudfiles-uk
--client-cidrs A comma-separated list of CIDR blocks.
E.g. 208.128.0.0/11,108.128.0.0/11
--cluster-name The name of the cluster to operate on.
E.g. hadoopcluster.
--cluster-user The name of the user that Whirr will
create on all the cluster instances.
You have to use this user to login
to nodes.
--config Note that Whirr properties specified
in this file should all have a
whirr. prefix.
--credential The cloud credential.
--firewall-rules A comma-separated list of port
numbers. E.g. 8080,8181
--firewall-rules-role A comma-separated list of port
numbers. E.g. 8080,8181. Replace
'role' with an actual role name
--hardware-id The type of hardware to use for the
instance. This must be compatible
with the image ID.
--hardware-min-ram The minimum amount of instance memory.
E.g. 1024
--identity The cloud identity.
--image-id The ID of the image to use for
instances. If not specified then a
vanilla Linux image is chosen.
--instance-templates The number of instances to launch for
each set of roles. E.g. 1 hadoop-
namenode+hadoop-jobtracker, 10
hadoop-datanode+hadoop-tasktracker
--instance-templates-max-percent- The percentage of successfully started
failures instances for each set of roles. E.
g. 100 hadoop-namenode+hadoop-
jobtracker,60 hadoop-datanode+hadoop-
tasktracker means all instances with
the roles hadoop-namenode and hadoop-
jobtracker has to be successfully
started, and 60% of instances has to
be succcessfully started each with
the roles hadoop-datanode and hadoop-
tasktracker.
--instance-templates-minimum-number-of- The minimum numberof successfully
instances started instances for each set of
roles. E.g. 1 hadoop-namenode+hadoop-
jobtracker,6 hadoop-datanode+hadoop-
tasktracker means 1 instance with
the roles hadoop-namenode and hadoop-
jobtracker has to be successfully
started, and 6 instances has to be
successfully started each with the
roles hadoop-datanode and hadoop-
tasktracker.
--location-id The location to launch instances in.
If not specified then an arbitrary
location will be chosen.
--login-user Override the default login user used
to bootstrap whirr. E.g. ubuntu or
myuser:mypass.
--max-startup-retries The number of retries in case of
insufficient successfully started
instances. Default value is 1.
--private-key-file The filename of the private RSA key
used to connect to instances.
--provider The name of the cloud provider. E.g.
aws-ec2, cloudservers-uk
--public-key-file The filename of the public key used to
connect to instances.
--run-url-base The base URL for forming run urls
from. Change this to host your own
set of launch scripts.
--service-name (optional) The name of the service to
use. E.g. hadoop.
--state-store What kind of store to use for state
(local, blob or none). Defaults to
local.
--state-store-blob Blob name for state storage. Valid
only for the blob state store.
Defaults to whirr-
--state-store-container Container where to store state. Valid
only for the blob state store.
--terminate-all-on-launch-failure Whether or not to automatically
terminate all nodes when cluster
launch fails for some reason.
--version

没有这样的东西叫做 hadoop-jobtracer （注意缺少的k）
这就是Hadoop集群所需要的：
whirr.instance-templates=1 hadoop-namenode+hadoop-jobtracker, 1 hadoop-datanode+hadooptasktracker
whirr.hardware-id=m1.small # or larger - t1.micro is not a good choice
另外，请确保查看recipes / hadoop-ec2.properties以获取更多示例。
