Hi,
I'm using the Scala DSL for Spark SQL, but I'm not able to do joins. I
have two tables (backed by Parquet files) and I need to do a join
across them using a common field (user_id). This works fine using
standard SQL but not using the language-integrated DSL neither
t1.join(t2, on = 't1.user_id == t2.user_id)
Two issues this line:
1. use |===| instead of |==|
2. Add a single quote before |t2|
nor
t1.join(t2, on = Some('t1.user_id == t2.user_id))
work, or even compile. I could not find any examples of how to perform
a join using the DSL. Any pointers will be appreciated :)
Thanks
-Jerry
