Trino Delta Lake connector fails to read _last_checkpoint file from MinIO

[MammadTavakoli]

I'm experiencing an issue with Trino's Delta Lake connector when trying to query a Delta Lake table stored in MinIO. My setup involves Trino, MinIO, and Hive Metastore, all running in Docker containers using a Docker Compose file.

Here are the key details about my setup:

1. I can successfully create a Delta Lake table in dw.test and save data to it.
2. When I connect to Trino via DBeaver and try to select from dw.test, I get the following error:

SQL Error [84279297]: Query failed (#20241203_091353_00046_vdmsn): Error getting snapshot for dw.test

The Trino logs show the following error:

that i think it is:

Caused by: java.lang.IllegalArgumentException: No factory for location: s3a://warehouse/dw.db/test/_delta_log/_last_checkpoint

My Trino configuration in the Docker Compose file looks like this:

trino-coordinator:
  image: "trinodb/trino:latest"
  container_name: trino-coordinator
  ports:
    - 8080:8080  
  volumes:
    - ./trino/coordinator/etc/catalog:/etc/trino/catalog 
    - ./trino/coordinator/etc:/etc/trino  
  environment:
    - TRINO_CATALOG_PATH=/etc/trino/catalog  
  depends_on:
    - hive-metastore 
  networks:
    - dl-network
  deploy:
    resources:
      limits:
        cpus: '1'
        memory: 10G

My Delta Lake catalog configuration includes:

connector.name=delta_lake

# Hive Metastore details
hive.metastore.uri=thrift://hive-metastore:9083 

# MinIO details
s3.endpoint=http://minio:9000 
s3.aws-access-key=test 
s3.aws-secret-key=test12334567 
s3.path-style-access=true

I've also configured my Hive Metastore with the following environment variables:

environment:
  HIVE_METASTORE_DRIVER: org.postgresql.Driver
      
  HIVE_METASTORE_JDBC_URL: jdbc:postgresql://metastore_db:5432/metastore
  
  HIVE_METASTORE_USER: hive
  HIVE_METASTORE_PASSWORD: hive
  
  HIVE_METASTORE_WAREHOUSE_DIR: s3://warehouse/
  
  S3_ENDPOINT: http://minio:9000
  
  S3_ACCESS_KEY: test
  S3_SECRET_KEY: test12334567
  
  S3_PATH_STYLE_ACCESS: "true"

I've tried various queries, including SELECT * FROM dw.test, but I consistently get the error about failing to get the snapshot.

Could this be related to permissions issues with MinIO access? Or could it be a known issue with Trino and Delta Lake connectors?

Question

How can I troubleshoot this issue with Trino failing to read the _last_checkpoint file from MinIO? Are there any known issues or common solutions to this problem?

But this code for reading from that location run correctly:

from pyspark.sql import SparkSession
from delta.tables import DeltaTable


def get_spark_session():
    return (
        SparkSession.builder.appName("DeltaLakeApp")
        .config("spark.jars.packages", "io.delta:delta-core_2.12:3.2.1")
        .config("spark.sql.extensions", "io.delta.sql.DeltaSparkSessionExtension")
        .config("spark.sql.catalog.spark_catalog", "org.apache.spark.sql.delta.catalog.DeltaCatalog")
        .config("spark.hadoop.fs.s3a.endpoint", "http://minio:9000")\
        .config("spark.hadoop.fs.s3a.access.key", "test")\
        .config("spark.hadoop.fs.s3a.secret.key", "test12334567")\
        .getOrCreate()
    )

def main():     
    spark = get_spark_session()
     
    table_path = "s3a://warehouse/dw.db/test"
    df = DeltaTable.forPath(spark, table_path).toDF()
    df.show()
         
     
def run_job(spark, config):
     main()

Thank you for your help!

I believe this problem might have to do with TLS, I have a similar setup

• Iceberg REST catalog (lakekeeper)
• MinIO for storage

but trino cannot connect with a similar error

[2025-03-14 23:27:57] java.lang.IllegalArgumentException: No factory for location: s3://logs/warehouse/01959841-98cf-7ac2-a1f0-31fbed87eb56/0195984a-836b-7d12-acd7-64cb372aeb00/metadata/snap-7485439850542550630-1-a8418a60-4ee3-42fb-b97b-8c4e8b70f75e.avro

the file does exist, but I suspect it has to do either with STS coming from the catalog or something similar.

I'm able to query the data just fine using spark with this simple configuration:

/opt/spark/bin/spark-sql  \
  --conf spark.jars.ivy=/tmp/.ivy \
  --packages "org.apache.iceberg:iceberg-spark-runtime-3.5_2.12:1.8.0,org.apache.iceberg:iceberg-aws-bundle:1.8.0" \
  --conf spark.sql.extensions=org.apache.iceberg.spark.extensions.IcebergSparkSessionExtensions \
  --conf spark.sql.catalogImplementation=in-memory \
  --conf spark.sql.catalog.my_catalog=org.apache.iceberg.spark.SparkCatalog \
  --conf spark.sql.catalog.my_catalog.catalog-impl=org.apache.iceberg.rest.RESTCatalog \
  --conf spark.sql.catalog.my_catalog.warehouse=warehouse \
  --conf spark.sql.catalog.my_catalog.token=dummy \
  --conf spark.sql.catalog.my_catalog.uri=http://catalog-lakekeeper.catalog.svc.cluster.local:8181/catalog \
  --conf spark.driver.extraJavaOptions="-Djavax.net.ssl.trustStore=/tmp/.ivy/certs/cacerts -Djavax.net.ssl.trustStorePassword=$TRUSTSTORE_PASSWORD" \
  --conf spark.executor.extraJavaOptions="-Djavax.net.ssl.trustStore=/tmp/.ivy/certs/cacerts -Djavax.net.ssl.trustStorePassword=$TRUSTSTORE_PASSWORD"

I'm using a custom truststore since I my MinIO is sitting behind TLS, but I'm not sure if that's the reason why trino cannot query the data
