Lists and Maps in Hive GenericUDF

I have not been posting to this blog regularly. So going to post some links on Hive genericUDF links currently open on my browser. 

Few months ago, I started off with GenericUDF without bothering with UDFs. Now that i write GenericUDFs with non-primitive types, I’m hoping this is helping.

I seem to encounter all kinds of exceptions. Things related to “kryo” being all greek to me. I’m catching them all with default Exception. Hope to get better at this.
