Sketches deploy JAR is missing the datasketches library #3159

Closed GCHQDeveloper314 closed 7 months ago

GCHQDeveloper314 commented 7 months ago

Describe the bug The Sketches deploy JAR sketches-library-2.1.0-deploy.jar contains only com.clearspring.analytics:stream. It's missing the datasketches library also used in the sketches-library module. This JAR is used to bundle essential dependencies required by Gaffer Accumulo instances. The missing datasketches library results in failures if datasketches properties are used in a Gaffer graph with Accumulo.

To Reproduce Steps to reproduce the behaviour:

  1. Run the road-traffic example with Accumulo (as done by Gaffer docker) with Gaffer 2.1.0
  2. Submit a query on the data (e.g. GetAllElements)

Expected behaviour Should run the query as expect without errors and return results.

Stack trace and errors Error response from REST API after submitting query:

{
  "statusCode": 500,
  "status": "Internal Server Error",
  "simpleMessage": "org.apache.accumulo.core.clientImpl.AccumuloServerException: Error on server accumulo-tserver:9997"
}

Errors in Gaffer REST instance logs:
