-----------------------------------
Summary: Log exceptions in tryOrIOException
Key: SPARK-14149
URL: https://issues.apache.org/jira/browse/SPARK-14149
Project: Spark
Issue Type: Improvement
Components: Spark Core
Reporter: Reynold Xin
Assignee: Reynold Xin
We ran into a problem today debugging some class loading problem during
deserialization, and JVM was masking the underlying exception which made it
very difficult to debug.
We can however log the exceptions using try/catch ourselves in
serialization/deserialization. The good thing is that all these methods are
already using Utils.tryOrIOException, so we can just put the try catch and
logging in a single place.
