-----------------------------------------

Hi [~xgong]/ [~ozawa],
I feel the issue is valid and needs to be fixed, if one of you guys can take a look at the
approach and the patch i mentioned earlier it would be helpful to get this jira  moving.

> 1.Start RM with HA and ATS configured and run some yarn applications
> 2.Once applications are finished sucessfully start timeline server
> 3.Now failover HA form active to standby
> 4.Access timeline server URL <IP>:<PORT>/applicationhistory
