hive datatypes vs java datatypes



I'm rather new in hive. With a background in BI the sql part is rather easy, but I'm still struggling with the java side. One thing I'm losing a lot of time on are the objecttypes we need to use in an UDF for certain hive datatypes (using GenericUdf). 

I'm looking for a conversion table that maps hive datatypes to javadatatypes. Anyone has a link to something like this?
