Bryan Duxbury updated HBASE-407:
--------------------------------
Attachment: 407-v2.patch
Used a generic when creating my SoftReference on 629, and removed extra imports.
As far as the unchecked null, do you mean on the server.close(scannerId) line?
I don't agree. It's not going to try and close the scanner unless it managed to
open one, which means that server has to be not null to get the scannerId in
the first place.
> Client should cache region locations in an LRU structure

> should use an LRU mechanism to help manage memory more dynamically.
