Subject [jira] Commented: (HADOOP-1272) Extract InnerClasses from FSNamesystem into separate classes
Date Mon, 30 Apr 2007 20:56:15 GMT

Konstantin Shvachko commented on HADOOP-1272:
---------------------------------------------

Looks like we agreed with Dhruba that whether SafeModeInfo is separated from FSNamesystem
or not it should be reorganized in order to support fine-grained locking he is working on
now.
I am still not happy about how it is separated in this patch because it reduces functionality
and introduces code replication.
I propose to leave it as it is in the FSNamesystem and open a new Jira issue for separating
the SafeModeInfo.
I volunteer to do the separation.
It is important to proceed with all other inner classes.

> This will make the code cleaner. Also, it leads itself to a cleaner and easily understandable
finer-grain locking model.
