Insert non-null values from dataframe

[Selvam Raman]

Hi ,

Dataframe:
colA colB colC colD colE
1 2 3 4 5
1 2 3 null null
1 null null  null 5
null null  3 4 5

I want to insert dataframe to nosql database, where null occupies
values(Cassandra). so i have to insert the column which has non-null values
in the row.

Expected:

Record 1: (1,2,3,4,5)
Record 2:(1,2,3)
Record 3:(1,5)
Record 4:(3,4,5)
