How to write ambari custom service for kernel update that needs rebooting

[Jae-Hyuck Kwak]

Hi,
I am using ambari as big data management platform for our project.

I would like to add custom ambari services for cluster management tasks
of our bigdata cluster. One of them is kernel update which is frequently
occur in cluster management. (Think of a recent intel bugs:-))

But, one thing to consider is that the kernel update requires a reboot.

How can this be implemented by ambari srevice?

Any comments will be appreciated.

Thanks,

BR,
Jae-Hyuck
