Description

STR:

1) Install cluster with Ambari2.7.0.0 + HDP-3.0.0.0
2) Upgrade Ambari to 2.7.1.0

Yarn Timeline Service V2 Reader goes down after some time.

Reason: the placeholders in yarn.timeline-service.reader.webapp.address and yarn.timeline-service.reader.webapp.https.address are no longer replaced by the stack code so these values become empty. In this case the timeline reader will use the default ports which may conflict with other ports used by other components.
