Spark RDD join with CassandraRDD

[Priya Ch]

Hi All,

 I have the following scenario:

  There exists a booking table in cassandra, which holds the fields like,
bookingid, passengeName, contact etc etc.

Now in my spark streaming application, there is one class Booking which
acts as a container and holds all the field details -

class Booking
{
   val bookingid =...
   val passengerName = ...
   val contact = ...
   .
   .
   .
   .
}

when a new booking message comes in I populate the fields in the class
which create rdds of type RDD[Booking]. Now I have this rdd to cassandra
table Booking as rdd.saveToCassandra.

Lets say if I query on booking table I would get cassandraRDD[CassandraRow]
If I want to join RDD[Booking] with this cassandraRDD...how is it
possible...as these are of two different rdds ?

converting CassandraRDD to RDD[CassandraRow] would make things work ?

Thanks,
Padma Ch
