             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.
