> Some deployments can deploy two instances of ATS/AMS/JHS. However, there is code in Blueprint
config processing which assumes only one host for these component type and thus tries to compute
URLS using the SingleHostTopologyUpdater resulting in the following error:
> java.lang.IllegalArgumentException: Unable to update configuration property 'yarn.timeline-service.webapp.https.address'
with topology information. Component 'APP_TIMELINE_SERVER' is mapped to an invalid number
of hosts '2'.
> SingleHostTopologyUpdater   should not update the original value of  properties if they
already have a value, in case of having multiple instances of HISTORYSERVER and APP_TIMELINE_SERVER
components.
