我正在通过 AWS EMR 接口创建 EMR 集群，但这次我尝试使用 HIVE 和 s3。
到目前为止，我只是尝试做一些非常简单的事情：将表从现有的镶木地板文件创建到 hive 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]
虽然它在带有火花提交的本地上运行得很好：
./bin/spark-submit --packages org.apache.hadoop：hadoop-aws：2.7.3 --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-memory 6g --num-executors 1 ~/db_migration/make_metastore.py
具有相同文件的 EMR 上的相同配置(3 m5.xlarge - 只是为了测试(拒绝工作。
容器中的 stderr 真的很差(我把它放在一个代码片段中以提高帖子可读性(：

Command exiting with ret '1'我卡住了，我不知道该怎么做或继续调试这个。它的最佳实践是什么？
正如我所料，这是一个艰难的主题，因为各种方法都是可能的。
就我而言，错误，令人惊讶地在本地保持沉默是：
语法错误：第 106 行的文件python_file.py中的非 ASCII 字符"\xe2"，但未声明编码
但这并没有显示在stderr上，而且很难发现。
对于在调试 EMR 集群时遇到困难的任何人，我学到并想在这里分享的是完成以下步骤：
-
检查步骤 stderr(大多数情况下，这仅在您未正确预置实例与 Spark-submit 配置相比时才有用(
-
谷歌错误，即使大多数时候它根本没有用。就我而言，它是错误代码：13，这与在 spark-submit 中定义母版时代码中
SparkSession.master("local[*]")时出现问题有关，因此在这里完全无关 -
检查容器日志(在摘要 ->配置详细信息下(，首先检查标准输出，如果标准输出不够，则检查标准输出
一旦您对 EMR 感到满意，它就会非常简单，而这个答案只针对那些对此感到迷茫的人。
