I downloaded spark version spark-1.3.0-bin-hadoop2.4.
When the python version of sql.py is run the following error occurs:
[root@nde-dev8-template python]#
/root/spark-1.3.0-bin-hadoop2.4/bin/spark-submit sql.py
Spark assembly has been built with Hive, including Datanucleus jars on
classpath
Traceback (most recent call last):

line 22, in <module>
from pyspark.sql import Row, StructField, StructType, StringType,
IntegerType
ImportError: cannot import name StructField
----------------------------------------------------------------------
The sql.py version, spark-1.2.1-bin-hadoop2.4, does not throw the error:
[root@nde-dev8-template python]#
/root/spark-1.2.1-bin-hadoop2.4/bin/spark-submit sql.py

The same error occurs when using bin/pyspark shell.
>>> from pyspark.sql import StructField

Any advice for resolving? Thanks in advance.
