Description

Steps to reproduce :
1) Create a cluster with ambari-2.4.3+HDP-2.5.3
2) Do ambari upgrade to ambari-2.6.1
3) Do stack upgrade to HDP-2.6.4
After upgrade its not possible to add livy2(Livy2 is a spark2 component).

This issue is specific to rolling upgrade. I am able to add livy2 in express upgraded cluster
Also in EU cluster I see 'Upgrade service configs' step , this step is likely updating the spark2 livy2 configs. But I am not seeing this in RU cluster.

The reason is that the desired version of a cluster is not updated (only during cross-stack rolling upgrade)
