Error when writing dataframe to delta table

Hello all,

 

second time trying to post this, as the first try was marked as spam (???).

 

I try to write a dataframe back to a delta table and get an error. This is the code I use to create the dataframe:

 

 

dfCustomer = spark.read.table("LakehouseOperations.factCustomerBase")
dfScope = spark.read.table("LakehouseOperations.tecDataScopeSnapshots")

dfCustomerJoined = dfCustomer.join(dfScope, dfCustomer.snapshot_date == dfScope.scopeDate, "inner").drop("scopeDate", "scopeDateBuckets")

dfCustomerJoined.write.mode("overwrite").format("delta").option("overwriteSchema", "true").save("Tables/factCustomerBase")

 

 

Then I get the error, see the screenshots here:

How can I solve this? Thanks!

The solution was to change the spark session configuration via the workspace settings:

What it actually does / means... I don't know.

Hi @JayJay11 ,

Thanks for using Fabric Community.
As part of testing, can you try to create a new table.

dfCustomerJoined.write.mode("overwrite").format("delta").option("overwriteSchema", "true").save("Tables/factCustomerBaseJoined")

 
Let me know the output of it.
