Subject [jira] [Commented] (ACCUMULO-1003) what is the point of SecuritySerDe?
Date Wed, 30 Jan 2013 16:15:12 GMT


Eric Newton commented on ACCUMULO-1003:

I understand that it's to provide alternative serialization methods, but we already have the
extra level of indirection in the SecurityToken.  If I want faster/better serialization, can't
I just use a new class?  And since hadoop already has a mechanism for substituting different
classes for Writables, we can leverage that infrastructure for future improvements.  For example,
we've replaced the implementation of the objects written to the WAL between releases by updating
the classes and providing the Hadoop library with the translation.

This just looks overly complex. That's fine if it has a point.

not just make SecurityToken Writable?
