Error in - Explicit write, creating an entity in a CDM folder based on a pre-defined model
Closed this issue · 11 comments
UPLOAD CDM FILES FIRST
To run this example, first create a /Models/Contacts folder to your demo container in ADLS gen2,
then upload the provided Contacts.manifest.cdm.json, Person.cdm.json, Entity.cdm.json files
When I was trying to execute following code segment, I get - Entity definition model file "/Contacts/Person.cdm.json" not found., All the directories and files are in place as per above comments.
My directory structure is - adbdemofilesystem / Models / Contacts
Files under Contacts are - Contacts.manifest.cdm.json, Person.cdm.json, Entity.cdm.json files
Create the dataframe that matches the CDM definition of the entity, Person
df2 = spark.createDataFrame(spark.sparkContext.parallelize(data2, 1), schema2)
(df2.write.format("com.microsoft.cdm")
.option("storage", storageAccountName)
.option("manifestPath", container + "/Data/Contacts/root.manifest.cdm.json")
.option("entity", "Person")
.option("entityDefinitionModelRoot", container + "/Models")
.option("entityDefinitionPath", "/Contacts/Person.cdm.json/Person")
.mode("overwrite")
.save())

That looks similar to what I have.
Can you also take a snapshot of the contents at the container level? Is there a directory called ImplicitTest at the same level Models?
I'm not sure what the error is then. Can you reach out to asksparkcdm@microsoft.com and we can schedule some time to debug it.
thank you for your help. I am closing this issue.
