Subject [jira] Commented: (HADOOP-6443) Serialization classes accept invalid metadata
Date Wed, 16 Dec 2009 02:16:18 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12791131#action_12791131

Aaron Kimball commented on HADOOP-6443:

The accept methods of the serializers check whether SERIALIZATION_CLASS equals the current
class name. If so, they accept unconditionally, even though they contain further (unreachable)
logic to ensure that they contain the requisite metadata (e.g., an avro schema or a class

The check should work in the opposite direction: if the user specifies SERIALIZATION_CLASS
and it does not equal the current class name, then the serialization should reject the metadata.
If the SERIALIZATION_CLASS equals the current class name, or is simply unset, then the serialization
should inspect the remainder of the metadata to ensure that it meets the criteria associated
with the current serialization.

incorrect metadata when determining whether they are the correct serializer for the user's
