The classifier has an option to enter the column names if your columns are not dynamic.
If that would not work, you could try one of the following:
-
Change the column names in the Data Catalog, set the SchemaChangePolicy to LOG, and set the partition output configuration to InheritFromTable for future crawler runs.
-
Create a custom grok classifier to parse the data and assign the columns that you want.
