pyspark hiveContext 错误，同时执行 spark-submit 应用程序到纱线和远程 CDH kerberized env

Question

执行时发生错误

airflow@41166b660d82:~$ spark-submit --master yarn --deploy-mode cluster --keytab keytab_name.keytab --principal --jars keytab_name@REALM --jars /path/to/spark-hive_2.11-2.3.0.jar sranje.py

来自 airflow docker 容器不在 CDH 环境中（不由 CDH CM 管理）。 sranje.py 是简单的 select * 来自 hive 表。

应用程序在 CDH 纱线上被接受并执行两次，但出现以下错误：

...

我们假设缺少“some.jar 和 java 依赖项”。 有任何想法吗？

细节

1. 在执行 spark cmd 之前有一个有效的 krb 票证
2. 如果我们省略--jars /path/to/spark-hive_2.11-2.3.0.jar ，pyhton 错误是不同的

...
pyspark.sql.utils.IllegalArgumentException: u"Error while instantiating 'org.apache.spark.sql.hive.HiveSessionStateBuilder':"
...

3. spark(2.3.0)、hadoop(2.6.0) 和 java 的版本与 CDH 相同
4. hive-site.xml, yarn-site.xml 等也提供且有效
5. 这个相同的 spark-submit 应用程序从 CDH 集群内的节点执行 OK
6. we tried adding additional --jars spark-hive_2.11-2.3.0.jar,spark-core_2.11-2.3.0.jar,spark-sql_2.11-2.3.0.jar,hive-hcatalog-core-2.3.0.jar,spark-hive-thriftserver_2.11-2.3.0.jar
7. 开发人员使用此代码作为示例：

# -*- coding: utf-8 -*-
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
from pyspark.context import SparkContext
from pyspark.sql import SparkSession, SQLContext, HiveContext, functions as F
from pyspark.sql.utils import AnalysisException
from datetime import datetime

sc = SparkContext.getOrCreate()
spark = SparkSession(sc)
sqlContext = SQLContext(sc)
hiveContext = HiveContext(sc)

current_date = str(datetime.now().strftime('%Y-%m-%d'))

hive_source = "lnz_ch.lnz_cfg_codebook"
source_df = hiveContext.table(hive_source).na.fill("")

print("Number of records: {}".format(source_df.count()))
print("First 20 rows of the table:")
source_df.show(20)

8. 不同的脚本，相同的错误

# -*- coding: utf-8 -*-
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
from pyspark.sql.types import *
from pyspark.sql.functions import *
from pyspark.sql import SparkSession

if __name__ == "__main__":
    spark = SparkSession.builder.appName("ZekoTest").enableHiveSupport().getOrCreate()
    data = spark.sql("SELECT * FROM lnz_ch.lnz_cfg_codebook")
    data.show(20)
    spark.close()

谢谢你。

Hive 依赖项通过以下方式解决：

• 下载hive.tar.gz与 CDH Hive 的确切版本
• 创建了从 hive/ 到 spark/ 的符号链接ln -s apache-hive-1.1.0-bin/lib/*.jar spark-2.3.0-bin-without-hadoop/jars/
• 额外的 jars 从 maven repo 下载到 spark/jars/

hive-hcatalog-core-2.3.0.jar
slf4j-api-1.7.26.jar
spark-hive_2.11-2.3.0.jar
spark-hive-thriftserver_2.11-2.3.0.jar

• 刷新环境变量

HADOOP_CLASSPATH=$(find $HADOOP_HOME -name '*.jar' | xargs echo | tr ' ' ':')
SPARK_DIST_CLASSPATH=$(hadoop classpath)

直线工作，但 pyspark 抛出错误

但是，这是另一个问题。 谢谢你们。
