AWS glue header doesn't work properly

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.
