Description
When deploying Paimon-Trino connector in Kubernetes with a custom Trino
image (based on trinodb/trino:440), I get the following error during startup:
```2026-02-10T08:01:29.746Z ERROR main io.trino.server.Server
io/trino/hdfs/HdfsModule
java.lang.NoClassDefFoundError: io/trino/hdfs/HdfsModule
at
org.apache.paimon.trino.TrinoConnectorFactory.create(TrinoConnectorFactory.java:103)
at
org.apache.paimon.trino.TrinoConnectorFactory.create(TrinoConnectorFactory.java:80)
at
io.trino.connector.DefaultCatalogFactory.createConnector(DefaultCatalogFactory.java:200)
...
```
Setup details
- Trino version: 440 (official trinodb/trino:440 image)
- Paimon-Trino version: 1.3.1 (built from source with -Dtrino.version=440)
- Build command: mvn clean install -DskipTests -Dtrino.version=440
-Dspotless.check.skip=true
- Plugin installation: all jars from
target/paimon-trino-440-1.3.1-plugin.tar.gz copied to
/usr/lib/trino/plugin/paimon/
- **Removed** from plugin directory: hadoop-apache-*.jar, hive-thrift-*.jar,
trino-hdfs-440.jar (Hadoop/HDFS not needed, only S3/MinIO)
Catalog properties (etc/catalog/paimon.properties):
```
connector.name=paimon
paimon.catalog.type=filesystem
fs.native.classpath.enabled=true
s3.endpoint=http://***:9000
s3.aws-access-key=***
s3.aws-secret-key=***
s3.path-style-access=true
s3.ssl.enabled=false
paimon.warehouse=s3a://paimon-dev/warehouse/
paimon.file.format=parquet
```
If I do NOT remove hdfs*/hadoop* jars from the plugin directory, the error
changes to:
```
2026-02-10T08:18:52.346Z ERROR main io.trino.server.Server Configuration
errors:
Error: An exception was caught and reported. Message: HDFS should not be on
the plugin classpath
at
ConfigurationFactory.registerConfigurationClasses(ConfigurationFactory.java:186)
...
```
In older issues (#96, #101, #119) people solved "HDFS should not be on the
plugin classpath" by moving Hadoop jars to paimon/hdfs/ subdirectory or
patching HdfsFileSystemLoader.java in Trino, but this does not solve.
Thank you!
