(Updated Jan. 12, 2016, 3:52 p.m.)


Review request for Ambari, Laszlo Puskas, Robert Nettleton, Sandor Magyari, Sumit Mohanty,
and Sebastian Toader.


Changes
-------

removed unused 'isOverrideHostRoleNeeded' method


Bugs: AMBARI-14491
    https://issues.apache.org/jira/browse/AMBARI-14491


Repository: ambari


Description
-------

With Blueprint deployments, zookeeper cannot be installed after manual upscale (it can happen
with any other services too).
That happened because of wrong cluster info.
Solution: 
- check logical request state before adding them to the cluster info (as pending components)


Diffs (updated)

Diff: https://reviews.apache.org/r/41925/diff/


Testing
-------

Unit tests done (SUCCESS).
Functional tests:
- deploy 1 node bp cluster (with zookeeper server). added 1 new host. install zookeper server
-> success.
- deploy 3-node cluster (namenode HA) -> move namenode -> cluster info is correct (service
check contains the correct nodes)


Thanks,

Oliver Szabo
