Give more information about a missing Serializer class
------------------------------------------------------

                 Key: HADOOP-7328
                 URL: https://issues.apache.org/jira/browse/HADOOP-7328
             Project: Hadoop Common
          Issue Type: Improvement
          Components: io
    Affects Versions: 0.20.2
            Reporter: Harsh J Chouraria
            Assignee: Harsh J Chouraria
             Fix For: 0.23.0


When you have a key/value class that's non Writable and you forget to attach io.serializers
for the same, an NPE is thrown by the tasks with no information on why or what's missing and
what led to it. I think a better exception can be thrown by SerializationFactory instead of
an NPE when a class is not found accepted by any of the loaded ones.
