Charles Lamb updated HDFS-7331:
-------------------------------
Attachment: HDFS-7331.003.patch
[~wheat9], [~atm],
Thanks for the comments and suggestions. Attached is the .003 patch which
removes the servlet, defaults the size of the bounded cache to Int.MAX_VALUE,
and uses only the hostname/address (without the port) as the key to the cache.
