Hi @jagadeesan here is the short update. After numerous failed attempts to build SPARK_HADOOP_VERSION=2.3.0.cloudera4 we added airflow node to CDH env. That was done by installing cloudera agent and registering the node to ClouderaManager. Next step was to edit docker-compose airflow.yaml file: -volumes mount ...

Hi @jagadeesan thank you for your reply. This airflow docker node is not in Cloudera environment, it's spark, hive, hadoop and java dependencies are not managed by CDH CM node. CDH 5.15 comes with spark 2.3.0, hadoop 2.6.0, hive 1.1.0 and java8 version. To submit a job to yarn, all versions must be the same (I know I've read this somewhere, I'm not going crazy yet :D). That's why we downloaded spark-2.3.0-bin-without-hadoop, hive-1.1.0 and so on. We even tried to build CDH spark. SPARK_HADOOP_VERSION=2.3.0.cloudera4 SPARK_YARN=true sbt assembly But it throws error: [warn] module not found: org.apache.hadoop#hadoop-client;2.6.0-cdh5.13.3
[warn] ==== public: tried
[warn] https://repo1.maven.org/maven2/org/apache/hadoop/hadoop-client/2.6.0-cdh5.13.3/hadoop-client-2.6.0-cdh5.13.3.pom Our next shot is to add this airflow node in CDH env and assign spark, hive and hdfs gateways. Apparently, this type of node does not need additional license...

Hi all, we are executing pyspark and spark-submit to kerberized CDH 5.15v from remote airflow docker container not managed by CDH CM node, e.g. airflow container is not in CDH env. Versions of hive, spark and java are the same as on CDH. There is a valid kerberos ticket before executing spark-submit or pyspark. Python script: from pyspark.sql import SparkSession, functions as F
spark = SparkSession.builder.enableHiveSupport().appName('appName').getOrCreate()
sa_df=spark.sql("SELECT * FROM lnz_ch.lnz_cfg_codebook") Error is: To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

at java.lang.Thread.run(Thread.java:748) Same error is retured from yarn when executing spark-submit. Details: googling this error, we assume that the versions of spark and hive in airflow container are "somehow mismatched". Error still occurs if we specify spark-submit or pyspark like this: spark-shell \
