Filter on a column having multiple values

[Ashok Kumar]

 Hi,
I would like to do the following
select count(*) from <table> where column1 in (1,5))
I define
scala> var t = HiveContext.table("table")
This workst.filter($"column1" ===1)
How can I expand this to have column1  for both 1 and 5 please?
thanks
