Subject Re: How to insert complex types like map<string,map<string,int>> in spark sql
Date Wed, 26 Nov 2014 17:35:00 GMT
Hi,
I guess this is fixed by https://github.com/apache/spark/pull/3110
which is not for complex type casting but makes inserting into hive
table be able to handle complex types ignoring nullability.

I also sent a pull-request (https://github.com/apache/spark/pull/3150)
for complex type casting before.
Please check it if #3110 doesn't work.

Thanks.
