pyspark.sql.utils.ParseException: u"\nextraneous > input 'xxx' expecting {')', ','} - sql

Question

I have 2 main tables: flights and holidays.
Flights is identified by: outboundlegid, inboundlegid, agent, querydatetime. The additional columns applicable to the question are out_date, in_date. They indicate when is the flight departing and the return date.
And Holidays with the columns start, end, type
I want to determine if the flight out/in date is intersecting any thing from holidays table.
I followed some suggestion from PySpark: How to add columns whose data come from a query (similar to subquery for each row) to determine if the out/in dates intersect any holiday.
However, I am getting: "pyspark.sql.utils.ParseException: u"\nextraneous
input 'outboundlegid' expecting {')', ','}(line 35, pos 12)". Whats wrong here?
