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

[~umamaheswararao] 

In small cluster, if there is restart, failure chances of meeting retry count 
"5" is high,

But for large cluster, the possibility is lesser.

Increasing retry from "5" to "10" or higher will increase the success chances 
for rolling restart case.

*As proper solution* when doing explicit rolling restart, we may need,
 * notify SCM for node's pipeline to be read-only for the duration, so that 
this will not impact system
