Amareshwari Sri Ramadasu commented on HADOOP-2178:
--------------------------------------------------
To address both the issues (HADOOP-1876 and this), we will store job history
files in a centralized location like
_{/logs/history/<jobtracker.hostname>_<user.name>_<jobid>}_ on DFS. This
location will avoid name conficts among users and hostnames.
The job history viewer(centralized) can display available history files and
user can select the job he wants to view from there.
For 1876, job status can be queried giving the jobid and hostname.
