UC_COMMAND_NOT_SUPPORTED.WITHOUT_RECOMMENDATION in shared access mode

I'm using a shared access cluster and am getting this error while trying to upload to Qdrant. This is the error. Anyway I can make it worked on shared access mode? It works on the personal cluster.

[UC_COMMAND_NOT_SUPPORTED.WITHOUT_RECOMMENDATION] The command(s): AppendData are not supported in Unity Catalog.  SQLSTATE: 0AKUC

 This is the code.

#embeddings_df = embeddings_df.limit(5)

    "vector_names": "dense",
    "schema": embeddings_df.schema.json(),
    "batch_size":"128",
}

embeddings_df.write.format("io.qdrant.spark.Qdrant").options(**options).mode(
    "append"
).save()

Hi @Awoke101

  • Shared access clusters in Databricks have certain restrictions due to Unity Catalog limitations.
  • I recommend trying the single-user Unity Catalog cluster or configuring data persistence outside the container. Let me know if you need further assistance!
