我正在使用AWS StepFunctions在Google Cloud方面执行多项任务-创建Dataproc集群,向其提交任务,然后将其拆除(每个都有其自己的Task状态,以及“轮询器”检查作业何时完成以移至下一个任务的任务)。
问题是,为了拆除群集,任务进入了“已取消”(灰色)状态,而不是“进行中”,随后是轮询器任务。一旦群集删除lambda函数执行了群集删除方法,它应该继续进行轮询器Task。
这里是集群删除lambda函数的一个例子:
from pprint import pprint
from google.cloud import storage
import googleapiclient.discovery
from rkstr8.cloud.google import GoogleCloudLambdaAuth
import time
def handler(event, context):
creds = event['GCP_creds']
GoogleCloudLambdaAuth(creds).configure_google_creds()
dataproc = googleapiclient.discovery.build('dataproc', 'v1')
project_id = event['gcp-administrative']['project']
zone = event['gcp-administrative']['zone']
try:
region_as_list = zone.split('-')[:-1]
region = '-'.join(region_as_list)
except (AttributeError, IndexError, ValueError):
raise ValueError('Invalid zone provided, please check your input.')
cluster = event['dataproc-administrative']['cluster_name']
print('Tearing down cluster...')
request = dataproc.projects().regions().clusters().delete(
projectId=project_id,
region=region,
clusterName=cluster)
time.sleep(30)
result = request.execute()
return result
状态机构建代码的相关部分如下所示:
dproc_submit_state = AsyncPoller(
stats_path=DPROC_SUBMIT_POLLER_STATUS_PATH,
async_task=Task(
name=DPROC_SUBMIT,
resource=DPROC_SUBMIT_ARN_VAR,
input_path=DPROC_SUBMIT_INPUT_PATH,
result_path=DPROC_SUBMIT_RESULT_PATH,
next=DPROC_SUBMIT_POLLER
),
pollr_task=Task(
name=DPROC_SUBMIT_POLLER,
resource=DPROC_SUBMIT_POLLER_ARN_VAR,
input_path=DPROC_SUBMIT_RESULT_PATH,
result_path=DPROC_SUBMIT_POLLER_STATUS_PATH
),
faild_task=Fail(
name='HailScriptFailed'
),
succd_task=DPROC_DELETE,
pollr_wait_time=self.conf["POLLER_WAIT_TIME"]
).states()
dproc_delete_state = AsyncPoller(
stats_path=DPROC_DELETE_POLLER_STATUS_PATH,
async_task=Task(
name=DPROC_DELETE,
resource=DPROC_DELETE_ARN_VAR,
input_path=DPROC_DELETE_INPUT_PATH,
result_path=DPROC_DELETE_RESULT_PATH,
next=DPROC_DELETE_POLLER
),
pollr_task=Task(
name=DPROC_DELETE_POLLER,
resource=DPROC_DELETE_POLLER_ARN_VAR,
input_path=DPROC_DELETE_RESULT_PATH,
result_path=DPROC_DELETE_POLLER_STATUS_PATH
),
faild_task=Fail(
name='ClusterDeleteFailed'
),
succd_task='PipelineSucceeded',
pollr_wait_time=self.conf["POLLER_WAIT_TIME"]
).states()
这是状态机的样子:
答案 0 :(得分:1)
为什么在创建请求和执行请求之间要睡30秒钟?
lambda的默认超时为3秒。我的猜测是您的lambda即将超时。
