I am trying to run the new apache pulsar Lakehouse Sink Connector and I am getting java.lang.IllegalArgumentException

Below is my setup. docker-compose.yaml file:

• I download the connector for here and copied the NAR package to the Pulsar connectors directory $PULSAR_HOME/connectors in the container.

• I logged in to miniO from http://localhost:9001/login and created a bucket call lakehouse.

• I used the cconfiguration similar to one described here and ureplacing the tablePath value with my miniO path. I named the file sink-connector-config.json.

{
  "tenant":"public",
  "namespace":"default",
  "name":"delta_sink",
  "parallelism":1,
  "inputs": [
    "test-delta-pulsar"
  ],
  "archive": "connectors/pulsar-io-lakehouse-2.9.3.7-cloud.nar",
  "processingGuarantees":"EFFECTIVELY_ONCE",
  "configs":{
      "type":"delta",
      "maxCommitInterval":120,
      "maxRecordsPerCommit":10000000,
      "tablePath": "s3a://lakehouse/delta_sink",
      "hadoop.fs.s3a.aws.credentials.provider": "com.amazonaws.auth.DefaultAWSCredentialsProviderChain"
  }
}

• I ran the lakehouse sink connector from the container. docker exec -it <container name> bash

then I executed

PULSAR_HOME/bin/pulsar-admin sink localrun \
--sink-config-file sink-connector-config.json

And I got the error below;

CodePudding user response：

Since you are running this as a bild-in connector, have you confirmed that the connector is available, e.g. $ pulsar-admin sinks available-sinks

Have you tried running it as non-built-in connector, e.g.

PULSAR_HOME/bin/pulsar-admin sinks create \
--sink-config-file <lakehouse-sink-config.yaml>

CodePudding user response：

Take a look at my example

https://github.com/tspannhw/FLiP-Pi-DeltaLake-Thermal

You may need the file type

configs: type: "delta" maxCommitInterval: 120 maxRecordsPerCommit: 10_000_000 tablePath: "file:///opt/demo/lakehouse" processingGuarantees: "EXACTLY_ONCE" deltaFileType: "parquet" subscriptionType: "Failover"

Also don't do a localrun, do a create

bin/pulsar-admin sinks create --archive ./connectors/pulsar-io-lakehouse-2.9.2.24.nar --tenant public --namespace default --name delta_sink --sink-config-file conf/deltalakesink.yml --inputs "persistent://public/default/pi-sensors" --parallelism 1 --subs-name pisensorwatch --processing-guarantees EFFECTIVELY_ONCE

Also try the YML configuration not JSON
