Combine key-value pair in spark java

[Ramkumar V]

Hi,

I have key value pair of JavaRDD (JavaPairRDD rdd) but i
want to concatenate into one RDD String (JavaRDD result ).

How can i do that ? What i have to use (map,flatmap)? can anyone please
give me the syntax for this in java ?

*Thanks*,

You should be able to use a simple mapping:

rdd.map(tuple -> tuple._1() + tuple._2())
