Counters in Hadoop

[Kris Jirapinyo]

Hi all,
    I am using counters in Hadoop via the reporter.  I can see this custom
counter fine after I run my job.  However, if somehow I restart the cluster,
then when I look into the Hadoop Job History, I can't seem to find the
information of my previous counter values anywhere.  Where is it stored (or
is it not)?  Also, I need to be able to write this counter value to either a
local file or even to a file in HDFS...is there a good way to do that?
