Brad Willard commented on SPARK-8128:
-------------------------------------
Initially I had through this was a bug related to the same attribute name being
reused in the nested structure. I've actually experienced this now with other
columns that have unique names. With a data file of 25 million records of this
schema I was able to get the same exception. I also want to note that I'm
building these parquet files with Spark Itself from json files.
This seems like a definite bug with the schema merging.

> Components: PySpark, Spark Core
> Affects Versions: 1.3.1
> Reporter: Brad Willard
>
> I'm loading a folder of parquet files with about 600 parquet files and
> loading it into one dataframe so schema merging is involved. There is some
> bug with the schema merging that you print the schema and it shows and
> attributes. However when you run a query and filter on that attribute is
> errors saying it's not in the schema.
> I think this bug could be related to an attribute name being reused in a
> nested object. "mediaProcessingState" appears twice in the schema and is the
> problem.
