-------------------------------------------
Summary: RU - Bug fixes for Host Version transition and Finalize
Key: AMBARI-9805
URL: https://issues.apache.org/jira/browse/AMBARI-9805
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.0.0
Reporter: Alejandro Fernandez
Assignee: Alejandro Fernandez
Fix For: 2.0.0
1. There is a bug in ServiceComponentHostSummary.java since its constructor
should not be comparing against the string UKNOWN, but rather rely on
ComponentInfo to determine which components need to advertise a version. Also,
the function haveAllComponentsFinishedAdvertisingVersion should instead compare
the size of all components that can advertise a version, and the subset of
those that have done so already.
2. ClusterImpl.java has a bug in transitionHostVersionState() when setting the
state to UPGRADING if the Host has exactly one Component with a version.
3. FinalizeUpgradeAction.java has redundant code now that AMBARI-9755 is in
because the call to transitionClusterVersion() will also take care of
transitioning HostVersions from INSTALLED->CURRENT for hosts that only have
components that do not advertise a version.
It is of the utmost importance to test these changes in the following scenarios:
Host added during cluster install
Host added after cluster install
Host added after bits are distributed
A Host may be added with either 0 services, only services that do not advertise
a version, or at least one service that advertises a version.
