Owen O'Malley updated HADOOP-1549:
----------------------------------
Status: Open (was: Patch Available)
I'd suggest keeping the serialization format the same and moving the old style
of
4 byte int len, bytes.
Changing the serialization format of writables is pretty much impossible at
this point, because we don't have any version information. Since they can be
stored in files forever, it isn't possible to update them.
> All remaining UTF8 data structures in HDFS code should be removed
