I'm writing a Spark streaming job and want to find out what's in my List
, ArrayList
, or what my return integers are.
This part of my code is supposed to print an integer result of a calculation:
println(math.floor(insights2.getTweetsFromCassandra(param1, pram2)).toInt)
However, when I run the streaming job, I get this output:
ResultSet[ exhausted: false, Columns[target(varchar)]]
How can I print out actual values instead, whether an integer or list?
