pyspark - 在集群模式下运行作业时，在 dataproc 中哪里可以找到 spark 日志

Question

我在 dataproc 中运行以下代码作为作业。 在“集群”模式下运行时，我无法在控制台中找到日志。

import sys
import time
from datetime import datetime

from pyspark.sql import SparkSession

start_time = datetime.utcnow()

spark = SparkSession.builder.appName("check_confs").getOrCreate()

all_conf = spark.sparkContext.getConf().getAll()
print("\n\n=====\nExecuting at {}".format(datetime.utcnow()))
print(all_conf)
print("\n\n======================\n\n\n")
incoming_args = sys.argv
if len(incoming_args) > 1:
    sleep_time = int(incoming_args[1])
    print("Sleep time is {} seconds".format(sleep_time))
    if sleep_time > 0:
        time.sleep(sleep_time)

end_time = datetime.utcnow()
time_taken = (end_time - start_time).total_seconds()
print("Script execution completed in {} seconds".format(time_taken))

如果我使用 deployMode as cluster 属性触发作业，我看不到相应的日志。 但是如果作业在默认模式下触发，即 client 模式，则能够看到相应的日志。 我已经给出了用于触发作业的字典。

"spark.submit.deployMode": "集群"

{
        'placement': {
            'cluster_name': dataproc_cluster
        },
        'pyspark_job': {
            'main_python_file_uri': "gs://" + compute_storage + "/" + job_file,
            'args': trigger_params,
            "properties": {
                "spark.submit.deployMode": "cluster",
                "spark.executor.memory": "3155m",
                "spark.scheduler.mode": "FAIR",
            }
        }
    }

在客户端模式下运行时控制台中没有日志

在集群模式下运行作业时，驱动程序日志位于 Cloud Logging yarn-userlogs 中。查看doc :

By default, Dataproc runs Spark jobs in client mode, and streams the driver output for viewing as explained, below. However, if the user creates the Dataproc cluster by setting cluster properties to --properties spark:spark.submit.deployMode=cluster or submits the job in cluster mode by setting job properties to --properties spark.submit.deployMode=cluster, driver output is listed in YARN userlogs, which can be accessed in Logging.
