I am running Apache Spark on YARN with Hive Metastore and PostgreSQL on an edge node, and HDFS with NodeManagers on five worker nodes.
The setup is as follows:
--network host
):
When executing a Spark job in client mode, everything works correctly. However, in cluster mode, the job fails with the following error:
PYTHONTraceback (most recent call last): File "/usr/local/hadoop/yarn/nodemanager/data/usercache/spark/appcache/application_1738582462412_0011/container_1738582462412_0011_02_000001/test_query.py", line 8, in <module> spark.sql("SHOW DATABASES").show() java.lang.NoSuchFieldError: METASTOREURIS
The Hive Metastore configuration in Spark (spark-defaults.conf) is:
PROPERTIESspark.sql.catalog.spark_catalog=org.apache.iceberg.spark.SparkCatalog spark.sql.catalog.spark_catalog.type=hive spark.sql.catalog.spark_catalog.uri=thrift://hive-metastore:9083
Since Hive Metastore is running in a container with --network host
, I manually added the hostname mappings:
BASH127.0.0.1 localhost --add-host hive-metastore:192.168.225.208 --add-host spark-iceberg-notebook:192.168.225.208 --add-host dw2endev01.sme.astro:192.168.225.208 --add-host dw2endev01:192.168.225.208 --add-host dw2nndev01.sme.astro:192.168.225.209 ...
And the host machine has the following mappings:
BASH127.0.0.1 localhost 127.0.0.1 hive-metastore 127.0.0.1 spark-iceberg-notebook 192.168.225.208 dw2endev01.sme.astro dw2endev01 spark-iceberg-notebook hive-metastore 192.168.225.209 dw2nndev01.sme.astro dw2nndev01 sme-hadoop-cluster 192.168.225.210 dw2nndev02.sme.astro dw2nndev02 ...
/etc/hosts
file on worker nodes correctly resolves hive-metastore
.What could be causing the java.lang.NoSuchFieldError: METASTOREURIS
error in cluster mode? Is this a classpath conflict where different versions of Hive-related libraries are used on the cluster, or could it be a networking issue between Spark and Hive Metastore?

The error is most likely caused by a classpath conflict—specifically, a mismatch between the versions of Hive-related libraries (for example, the one that defines METASTOREURIS) loaded on the cluster versus the versions expected by Spark and Iceberg.
When you run in client mode, your local classpath might be masking the conflicting libraries. In cluster mode, the worker nodes load their own versions (from Spark’s packaged jars or the cluster’s Hive installation), causing a version mismatch that triggers the error.
Steps to Resolve:
Review Dependencies:
Check that the Hive and Iceberg jars on the worker nodes match the versions expected by your Spark job. You might need to exclude Spark’s bundled versions if you’re using your own Hive Metastore libraries.
Align Versions:
Ensure that Spark, Hive Metastore, and Iceberg are compiled and run against compatible versions. For example, if Spark’s internal Hive version is different from the one you’ve deployed on the edge, you may see this kind of error.
Classpath Isolation:
Consider using configuration options (like --jars or --driver-class-path) to explicitly control which jars are used, or use dependency shading to avoid conflicts.
In summary, the error is a classpath issue rather than a networking problem.
