Vinod K V updated MAPREDUCE-744:
--------------------------------
Component/s: security
distributed-cache
Release Note: Fixed DistributedCache to support sharing of the local cache
files with other users on the same TaskTracker. The cache files are checked at
the client side for public/private access on the file system, and that
information is passed in the configuration. The TaskTrackers look at the
configuration for each file during task localization, and, if the file was
public on the filesystem, they are localized to a common space for sharing by
all users' tasks on the TaskTracker. Else the file is localized to the user's
private directory on the local filesystem.
> Support in DistributedCache to share cache files with other users after
> HADOOP-4493
