问题
I'm trying to struct a schema for db testing, and StructType apparently isn't working for some reason. I'm following a tut, and it doesn't import any extra module.
<type 'exceptions.NameError'>, NameError("name 'StructType' is not defined",), <traceback object at 0x2b555f0>)
I'm on spark 1.4.0, and Ubuntu 12 if that has anything to do with the problem. How would I fix this problem? Thank you in advance.
回答1:
Did you import StructType? If not
from pyspark.sql.types import StructType
should solve the problem.
