I implemented jt ha on cdh4.4.2 . Jobtracker keeps on failing over to each 
other, job keeps restarting, also namenode goes down at times and I can see 
logs for few datanodes mentioning all data nodes are bad. aborting. 

I installed jt ha manually like this :-

After configuring jt ha i started jobtracker ha daemon using command after 
formatzk
Nohup Hadoop jobtrackerha &
Then i started mrzkfc using following commands
Nohup hadoop mrkfc &

Please advice me if I am doing anything wrong. Also is that right way to start 
the jt ha and failover controller ?
