Chris Douglas commented on HADOOP-1549:
---------------------------------------
The InterTrackerProtocol version needs to be bumped. SequenceFile's version
will also need a bump and code handling the change to its format, right? Can
this read serialized ArrayWritables written out prior to this patch?
> All remaining UTF8 data structures in HDFS code should be removed
