Hairong Kuang commented on HADOOP-1653:
---------------------------------------
The reason that we should not replace UTF8 with Text in FSEditLog is that their
serialized formats are different. The replacement changes the edit log's
on-disk format, causing backward compatibility problem when upgrading dfs.
