------------------------------------
Summary: Task listener overloads no longer needed with JDK 8+
Key: SPARK-40141
URL: https://issues.apache.org/jira/browse/SPARK-40141
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 3.3.0
Reporter: Ryan Johnson
TaskContext defines methods for registering completion and failure listeners,
and the respective listener types qualify as functional interfaces in JDK 8+.
This leads to awkward ambiguous overload errors with the overload of each
function, that takes a function directly instead of a listener. Now that JDK 8
is the minimum allowed, we can remove the unnecessary overloads, which not only
simplifies the code, but also removes a source of frustration since it can be
nearly impossible to predict when an ambiguous overload might be triggered.
