Issue with Column Name Conflict While Importing .gz File into Spark DataFrame

[Akshay_Petkar]

I'm encountering an issue while importing a .gz file containing JSON data into a Spark DataFrame in Databricks. The error indicates a column name conflict. Could you please advise on how to resolve this issue and handle duplicate column names during import?

Hi @Akshay_Petkar, By defining the schema explicitly, you can control how Spark interprets the columns. If you know which columns are causing conflicts, you can rename them during the read operation. Use selectExpr to Rename Columns. If the duplicate columns are not needed, you can drop them. Sometimes, conflicts arise from nested JSON structures. Ensure that nested fields are properly handled.
