Type VARCHAR(n) is not supported in Kudu error when creating table in Impala 3.4.0

Question

I'm trying to create a table with a varchar(30) column in Impala 3.4.0/Kudu 1.14.0 According to this Jira ticket it is exactly Impala 3.4.0 where support for varchar columns was included for the first time. Is there any problem with my understanding of this ticket, the syntax I use or something else that I need to fix to make this work? Did I forgot something when building or configuring Impala?
