How to use HCatalog on AWS EMR?

I am trying to use HCatalog with amazon EMR. According to the documentation it is possible, but i cannot find any description how I should configure it.

I guess i need to register some jars, but not sure.

I cannot find any programs or bootstrap actions on EMR page related to Hcatalog when creating new cluster. Could you help how i can set it up?

Thanks in advance.
