Kan Zhang updated HADOOP-6670:
------------------------------
Attachment: c6670-02.patch
Attaching a straight-forward port for trunk. Changes made to TestFileSystem in
the original patch is now applied to TestFileSystemCaching. Changes made to
FileSystem.java are ignored since only debug messages were added. Changes made
to TestTrackerDistributedCacheManager are also ignored for the same reason.
Devaraj's bug fix for Gridmix is not ported at this time since related Gridmix
files are not forward ported yet. It's better to incorporate the bug fix when
porting Gridmix.
> UserGroupInformation doesn't support use in hash tables

> The UserGroupInformation objects are mutable, but they are used as keys in
> hash tables. This leads to serious problems in the FileSystem cache and RPC
> connection cache. We need to change the hashCode to be the identity hash code
> of the Subject and change equals to use == between the Subjects.
