Subject [jira] Commented: (HADOOP-1272) Extract InnerClasses from FSNamesystem into separate classes
Date Mon, 23 Apr 2007 21:25:15 GMT

dhruba borthakur commented on HADOOP-1272:

Thanks for all the comments. In the first pass, I plan on breaking up FSNamesystem into the
classes that Konstantin has suggested. I agree that, this at first sight, might appear as
if we are moving clutter from inside FSNamesystem into the file-names in the dfs package.
I would still like to split out the Innerclasses from FSnamesystem into their own files. This
helps me in implementing file-grain lock per data structure (hadoop-1269) in a much cleaner
way. Once I am done with this splitting, then I will open another JIRA issue to reorder files
into packages.

Doug: please let me know if this sounds reasonable.

finer-grain locking model.
