Hairong Kuang commented on HDFS-544:
------------------------------------
"/current/finalized/" is not the finalized directory name. I created this
constant string just to avoid the occurrences of this string millions times in
the test. If we ever want to fix this problem, DataNode should provide a method
to return a list of "finalized" directories. But I think we should do it in a
different jira in trunk.
> Add a "rbw" sub directory to DataNode data directory
