问题
I am running a query on AWS EMR and the query errors out on this line -
to_date('1970-01-01', 'YYYY-MM-DD') + CAST(concat(mycolumn, ' seconds') AS INTERVAL) AS date_col
The error - DataType interval is not supported.(line 521, pos 82)
Can someone help me with this?

I think Spark supports the interval key word. It would be used as:
to_date('1970-01-01', 'YYYY-MM-DD') + mycolumn * interval '1 second' AS date_col
