Make sure we are using the context classloader when deserializing failed TaskResults instead of the Spark classloader. The issue is that `enqueueFailedTask` was using the incorrect classloader which results in `ClassNotFoundException`. Adds a test in TaskResultGetterSuite that compiles a custom exception, throws it on the executor, and asserts that Spark handles the TaskResult deserialization instead of returning `UnknownReason`. See #9367 for previous comments See SPARK-11195 for a full repro Author: Hurshal Patel <hpatel516@gmail.com> Closes #9779 from choochootrain/spark-11195-master. |
