I need to spilt RDD [keys, Iterable[Value]] to save each key into different file.
e.g I have records like: customerId, name, age, sex 111,abc,34,M 122, xyz,32,F 111,def,31,F 122.trp,30,F 133,jkl,35,M I need to write 3 different files based on customerId file1: 111,abc,34,M 111,def,31,F file2: 122, xyz,32,F 122.trp,30,F file3: 133,jkl,35,M How I can achieve this in spark scala code?
