Review request for Ambari, Alexander Denissov, bhuvnesh chaudhary, Mahadev
Konar, and Srimanth Gunturi.
Bugs: AMBARI-15589
https://issues.apache.org/jira/browse/AMBARI-15589
Repository: ambari
Description
-------
Stack Advisor recommendation overrides installed slaves topology of installed
services when a new service is added.
Steps to reproduce:
- Install a cluster with HDFS and HAWQ select HAWQSEGMENTs on hosts different
from the recommended set of hosts
- Install any other service (HBASE). Error: On the assign slaves page, the
HAWQSEGMENTs are checked according to recommendations and not according to the
current host topology.
The patch attached to this JIRA would fix the following issues:
- Recommendation given during Add Service wizard should be a combination of
current topology for installed services and recommendation for service that is
to be installed.
- Adding a new service after adding HAWQ or PXF would checkbox the HAWQSEGMENTs
and PXFs correctly even if the user has placed these components different from
the layout provided by the recommendation.
