我正在通过AWS EMR界面创建EMR集群，但是这次我尝试使用HIVE和s3。
到目前为止，我只是在尝试做一些非常简单的事情：从现有的实木复合地板文件创建表格到蜂巢中。
from pyspark.sql import SparkSession
warehouse_location = "s3a://bucket/databricks_warehouse"
data_location = "s3a://bucket/report_emr_interim"
def register_table(table_name, spark):
print(data_location + "/" + table_name)
data_location_final = data_location
if table_name == 'ds_ad_mapping':
data_location_final = 's3a://bucket/ds_report/parquet'
spark.read.parquet("{}/{}".format(data_location_final, table_name))\
.createOrReplaceTempView("{}_tmp".format(table_name))
spark.sql("CREATE TABLE IF NOT EXISTS {0} LIKE {0}_tmp LOCATION '{1}/{0}'".format(table_name, warehouse_location))
spark.sql("DESC {}".format(table_name))
if __name__ == "__main__":
spark = SparkSession.builder\
.appName("spark")\
.config("spark.executor.extraJavaOptions","-Dcom.amazonaws.services.s3.enableV4=true") \
.config("spark.driver.extraJavaOptions","-Dcom.amazonaws.services.s3.enableV4=true") \
.enableHiveSupport()\
.getOrCreate()
tables = [
"adwords_ad",
"adwords_adgroup",
"adwords_accounts",
"adwords_duration",
"adwords_duration_hour",
"ds_conversion",
"ds_visit",
"ds_visit_adgroup_engine_id",
"ds_conversion_adgroup_engine_id",
"ds3_adwords_adgroup_hourly",
"ds_ad_mapping",
"ds_conversion_adgroup_engine_id",
"sc_raw_report"
]
[register_table(table, spark) for table in tables]
尽管在本地使用spark-submit效果很好：
./ bin / spark-submit-打包org.apache.hadoop：hadoop-aws：2.7.3 --conf spark.hadoop.fs.s3a.impl = org.apache.hadoop.fs.s3a.S3AFileSystem --conf spark.hadoop.fs.s3a.access.key = AWS_ACCESS_KEY --conf spark.hadoop.fs.s3a.secret.key = AWS_ACCESS_KEY --conf spark.executor.memoryOverhead = 2g --driver-memory 5g- executor-cores 1 --executor内存6g --num-executors 1〜/ db_migration / make_metastore.py
在具有相同文件的EMR上使用相同的配置（3 m5.xlarge-仅用于测试）拒绝工作。
容器中的stderr确实很差（为了便于阅读，我将其放在代码段中）

我被困住了，我不知道该怎么办或继续调试它。最佳做法是什么？
答案 0 :(得分：0)
正如我所期待的那样，这是一个艰巨的课题，因为可以采用各种方法。
在我的情况下，本地错误出人意料地是：
SyntaxError：第106行的文件python_file.py中的非ASCII字符'\ xe2'，但未声明编码
但这在stderr上没有显示，很难发现。
我已学到的东西，并想与任何在调试EMR群集方面遇到困难的人分享一下，请遵循以下步骤：
检查步骤stderr（大多数情况下，仅当您未正确配置您的实例与spark-submit提交的配置相比，这才有用）
Google错误，即使大部分时间根本没有用。在我的案例中，它是errorCode：13，这与在代码中提交SparkSession.master("local[*]")时在spark-submit中定义母版时遇到的麻烦有关，因此在这里根本不相关
检查容器日志（在摘要->配置详细信息下），如果stdout不够，请先检查stdout，然后再检查stderr
一旦您对EMR感到放松，这非常简单，而且此答案仅针对那些对此感到迷茫的人。
