Glue Studio Designer: use pyspark functions

Question

I designed a glue job using Glue studio designer canvas feature and am using a custom transform in there. However, I am struggling to leverage functions like the ones from 'from pyspark.sql.functions import *' in the code as I get error "NameError: name xyz not defined.  
How can I leverage these functions in the canvas tool?

Accepted Answer

Hi ,

yes, any library you need for your custom transform should be imported within the function.

just to consider if you want to run SparkSQL you could also use the SQL transform.

hope this helps,

Answer

Try importing specific function instead of import *.  For example,  "from pyspark.sql.functions import split" to import split function.

I tried replicating your problem, it complained that import * can only be used at module level.  But when I changed to specific function, it worked.

Hope this help.
