> 2.6.4.0-91
> 2) Upgrade Ambari to Target Version: 2.6.2.0-67
> 3) Patch Express Upgrade Spark2 to HDP-2.6.5.0-120
> Observe the version of livy2-client after  PU
> result of hdp-select command
> {code:java}
> [root@ctr-e138-1518143905142-45389-01-000002 ~]# hdp-select | grep 
> livy2-client
> livy2-client - 2.6.4.0-91

> hdp-select outputs <See the livy2-client versions on all hosts , should have 
> been 2.6.4.0-120>
> {code:java}

> *Note : The livy2-client version was set correctly during Full stack Express 
> Upgrade. The issue is seen only for Patch Upgrade*
> LIVY2_CLIENT isn't actually a component which Ambari manages. That's why it's 
> never orchestrated. I suppose that we can fix this by having the 
> SPARK2_CLIENT also update the pointers for LIVY2_CLIENT by changing the 
> stack_packages.json.
