Subject [jira] Created: (HADOOP-6729) serializer.JavaSerialization should be added to io.serializations by default
Date Wed, 28 Apr 2010 02:40:33 GMT
serializer.JavaSerialization should be added to io.serializations by default
----------------------------------------------------------------------------

                 Key: HADOOP-6729
                 URL: https://issues.apache.org/jira/browse/HADOOP-6729
             Project: Hadoop Common
          Issue Type: Improvement
          Components: conf
    Affects Versions: 0.20.2
            Reporter: Ted Yu


org.apache.hadoop.io.serializer.JavaSerialization isn't included in io.serializations by default.

When a class which implements the Serializable interface is used, user would see the following
without serializer.JavaSerialization:

java.lang.NullPointerException
