Subject [jira] Commented: (HADOOP-3245) Provide ability to persist running jobs (extend HADOOP-1876)
Date Thu, 11 Sep 2008 15:57:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3245?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12630234#action_12630234
] 

Amar Kamat commented on HADOOP-3245:
------------------------------------

I have manually tested the patch w.r.t counter recovery and update. Some counters are recovered
using HADOOP-3970 while some are dynamically updated based on replay of events (job level
counters like DATA_LOCALITY etc). Have manually checked and found the counters upon restart
are very similar to the ones before the restart.

> This could probably extend the work done in HADOOP-1876. This feature can be applied
for things like jobs being able to survive jobtracker restarts.
