Alexis Seigneurin created SPARK-4557:
----------------------------------------
Summary: Spark Streaming' foreachRDD method should accept a
VoidFunction<...>, not a Function<..., Void>
Key: SPARK-4557
URL: https://issues.apache.org/jira/browse/SPARK-4557
Project: Spark
Issue Type: Bug
Affects Versions: 1.1.0
Reporter: Alexis Seigneurin
In *Java*, using Spark Streaming's foreachRDD function is quite verbose. You
have to write:
{code:java}
.foreachRDD(items -> {
...;
return null;
});
{code}
Instead of:
{code:java}
.foreachRDD(items -> ...);
{code}
This is because the foreachRDD method accepts a Function<JavaRDD<...>, Void>
instead of a VoidFunction<JavaRDD<...>>. This would make sense to change it to
a VoidFunction as, in Spark's API, the foreach method already accepts a
VoidFunction.
