Tutorial should be fixed with the correct delimiter; i.e. '\t' instead of 't' for. (back slashes are missing causing bad import of sample files)
Example from tuto:
create table products (url STRING, category STRING) ROW FORMAT DELIMITED FIELDS TERMINATED by 't' stored as textfile tblproperties ("skip.header.line.count"="1");
Four months? Perhaps you could give the Doc team a little nudge?
More generally, it's clear that HortonWorks have not checked these tutorials by having someone follow them through as written, perhaps that's something you should look at.
