FAQ
Hi,
When I kill job tracker process in a Hadoop cluster of 3 node instances,
everything collapsed.
I was solving a problem by map/reduce
and program bombed as job tracker is dead?
Is there any failover mechanism for job tracker??
Thanks
Servesh

    no there isn't any failover for JT as of now. It has to be started up
    manually.
