Subject FlatMap in DataFrame
Date Mon, 08 Jun 2015 04:36:56 GMT
Hi,
I'm trying to write a custom transformer in Spark ML and since that uses
DataFrames, am trying to use flatMap function in DataFrame class in Java.
Can you share a simple example of how to use the flatMap function to do word
count on single column of the DataFrame. Thanks.

Dimple
