Stas Levin updated BEAM-1713:
-----------------------------
Description:
When creating an anonymous class like so:
{code:java}new Iterable<byte[]>() {...}{code} it is capturing the enclosing
scope's {{SparkRuntimeContext}} instance in
{{StateSpecFunctions#mapSourceFunction}} via {code:java}return new
SerializableFunction3<Source<T>, Option<CheckpointMarkT>,
State<Tuple2<byte[], Instant>>, Tuple2<Iterable<byte[]>, Metadata>>() {
... runtimeContext usage ... } {code}
was:
