[Hadoop-common-dev] [jira] Created: (HADOOP-2739) SequenceFile and MapFile should either be subclassable or they should be declared final

SequenceFile and MapFile should either be subclassable or they should be declared final
---------------------------------------------------------------------------------------

Key: HADOOP-2739
URL: https://issues.apache.org/jira/browse/HADOOP-2739
Project: Hadoop Core
Issue Type: Bug
Components: io
Affects Versions: 0.16.0
Reporter: Jim Kellerman
Assignee: Jim Kellerman
Priority: Minor


Neither SequenceFile nor MapFile are currently subclassable as there are no accessor methods to their private members or member functions. Either protected accessor methods should be added or the member variables should be declared as protected instead of private.

OR

both SequenceFile and MapFile should be declared as final.
